Full textThe development of alternative propeller systems to turbojets is a main issue for research in the current context of aeronautical transport. Counter rotating open rotors are a candidate solution because they allow reduction of fuel consumption and gas emission. However, noise emissions are still a challenge for these types of configuration, in particular because they cannot benefit from the nacelle and the liners currently used in turbojet. The understanding of acoustic sources and their prediction is necessary in order to be able to reduce noise emission in the near future. Flows in an open-rotor are complex, in particular for the downstream propeller which is the subject of this approach.This work based on a numerical, experimental and analytical study and takes part in the ADOPSYS chair between Safran Aircraft Engines and l’Ecole Centrale de Lyon. This PhD has two main goals. The first one is to complete an experimental study in order to elucidate the behavior of the flow on a swept airfoil and the resulting acoustics, with a possibly developing leading-edge vortex. The measurements will be a data base for further comparison with analytical prediction. The second objective of the PhD consists in developing a semi-analytical modeling of the noise emitted by an airfoil in response to an incoming perturbation, taking into account the loading and geometry effects. A numerical study of a full counter-rotating system was used as a basis for designing the investigated airfoil. The latter was designed so that a leading-edge vortex could be formed on the surface for some angles of attack. The mock-up was then tested in an anechoic wind tunnel of Ecole Centrale de Lyon for various sets of parameters. Flow visualization and wall-pressure measurements indicated the presence of the leading-edge vortex for some angles of attack. The far-field measurements indicated three acoustic regimes, which can be associated with three behaviors of the leading-edge vortex. Source localization measurements corroborate these observations. Analytical predictions of the noise emitted by the airfoil and based on Amiet’s model were also performed. Firstly, the sweep angle is taken into account in the model. Secondly it is applied to the studied airfoil. A better match of the results is found when the sweep is considered, in particular in the perpendicular directions. The model in then extended in order to include the wall-junction. This part is exploratory and should be further developed. Finally, a complementary experimental investigation of the impingement of periodic wakes on the airfoil has been performed, using a system made of rotating bars, mimics true wake interactions. The measurements suggest that the leading-edge vortex has a quasi-steady behavior

Full textThis thesis deals with the electrical characterization of MOS transistors with ultra-thin oxinitride gate dielectrics in the range 2-7 nm. It also concerns the study of electrical active defects in oxinitride-silicon systems. In the first chapter, we review the main characteristics of the Si-Si02 electrical defects as well as the limitations of Si02 used as gate dielectric for deep-submicron MOSFET's. We also present the basic properties of oxinitride layers and we discuss the validity of such dielectrics as a possible alternative to the classical Si02. The second chapter is devoted to the analytical modeling of the MOS transistor working before saturation. We completely rewrite the electrical models that we use in this work to extract the electrical parameters of our devices. In chapter three, we develop a new model of the charge pumping current, taking into account the response of individual and/or distributed states in the silicon bandgap. This approach allows us to accurately model the two- and three-level techniques in terms of current components due to the trapping-detrapping mechanisms from interface states. Finally, we propose an experimental method to separate the charge pumping and the tunneling currents when performing measurements on ultra-thin gate oxide MOSFET's. Chapter fourth is dedicated to the theory of low frequency (1/f) noise in MOS devices. After reviewing the possible origins of this noise, we analyze the influence of the dielectric thickness scale-down and surface roughness on its level. We also propose an enhanced model and extraction procedure to determine the slow state density in presence of a parasitic tunneling component from the gate. In the final part of our work, we use the three electrical techniques, previously reported, to carefully investigate the electrical properties of n-channel MOSFET's with oxinitride gate dielectrics formed by law-pressure rapid thermal chemical vapor deposition (LPRTCVD). Important technological parameters, such as nitrogen concentration, ambient and temperature of post-deposition annealing treatments, presence of an additional capping-layer, etc. , have been analyzed in terms of the presence of fast and slow states and fi.

Full textThis work deals with the friction and dynamics of a sliding contact between two dry and rough surfaces subjected to a low normal load. The normal vibration and the resulting noise are associated with the excitation induced during slip by the random topographies of both solids. Experimental measurements of the vertical acceleration of a rough slider subjected to its own weight and steadily sliding on a rough plate enabled identification and characterization of a transition between two regimes: An uninterrupted contact regime at low speeds and a regime of jumps at higher speeds. For the latter, the dynamics are governed by many impacts between asperities that we have characterized statistically (number of shocks, duration between shocks, impact forces, etc.). These two regimes lead to distinct frictional behaviors. One of the originalities of this research was to confirm the scenarii suggested by the accelerometric measurements through high-frequency monitoring of the temporal evolution of the electrical contact resistance during sliding. By improving the temporal resolution of shocks, these measurements provide a dynamics picture of the problem of rough electrical contact. To interpret these experimental results, we have revisited the standard Bouncing Ball model. It describes a ball subjected to gravity, and bouncing on a table animated by a random vertical motion, representative of the stochastic excitation induced by the topographies of sliding surfaces. We improved the model by introducing a correlation time for the random excitation and showed its influence on the dynamics of the bounces. This correlation time is directly related to the correlation lengths of the surfaces in contact and to the sliding velocity. This revisited model enables a good prediction of the speed at which the transition between the two regimes is observed experimentally

Full textWe study the electronic properties of coupled semiconductor nanocrystals and carbon nanotubes. We report measurements of single electron transfers between single CdSe colloidal nanocrystal coupled to a carbon nanotube field effect transistor at room temperature in ambient conditions. The measurements consist of nanotube current level monitoring as a function of time for fixed gate voltage. We observe a sequence of high - low currents (random telegraph signal) on time scales up to several seconds with ms sampling time. We attribute the two level current fluctuations to the transfer of single electron onto the nanocrystal. The probability of the occupation time τ at the high or low current state follows a power law of the form P(τ)~τ-α where exponent α lies between 1.5 and 4 (typically close to 2.8). The observation suggests that the two-level current switching is similar to the fluorescence intermittency (optical blinking) observed in individual quantum dots. The spectroscopic analysis of the devices based on coupled semiconductor nanocrystals and carbon nanotubes is consistent with the charging of nanocrystal defect states with a charging energy of Ec ~ 200 meV. The approach developed here enables to probe the trap state dynamics in quantum dots in ambient air and room temperature from a purely electrical approach, and therefore to better understand the physics at hand in (opto)electronic devices based on quantum dots

Full textIn some quantum matter states, the current may remarkably be transported by carriers that bear a fraction e* of the elementary electron charge. This is the case for the Fractional quantum Hall effect (FQHE) that happens in two-dimensional systems at low temperature under a high perpendicular magnetic field. When the number of magnetic flux in units of h/e is a fraction of the number of electron, a dissipationless current flows along the edges of the sample and is carried by anyons with fractional charge. The observation of the fractional charge is realized through small current fluctuations produced by the granularity of the charge. Here is presented a reliable method to measure the fractional charge by the mean of cross-correlation of current fluctuations. Moreover, the dynamical properties of those charges is probed when the sample is irradiated with photos at GHz frequency. The long predicted Josephson frequency of the fractional charge is measured. Those measurements validate Photoassisted processes in the FQHE and enable timedomain manipulation of fractional charges in order to realize a single anyon source based on levitons to perform tests of the anyonic statistics of fractional charge
