Abstract:
Mobility degradation during gate length scaling is a well established experimental fact, which is confirmed also by Monte –Carlo simulation. We have analyzed the physical reason for this degradation using experimental and modeling data obtained in classic drift-diffusional approximation with electric field dependences of electron mobility. We have shown that this dependence is a main reason for mobility degradation in nanoscale FETs, which means also that the same reason will limit the drain current in future post-silicon CMOS generation with new materials like narrow band III/V compounds or g

In this study, we present results on electrical characterization of bipolar pn-diodes to investigate the temperature and electrical field dependent behavior of ambipolar mobility in n-doped 4H-SiC. Therefore, static current-voltage measurements to calculate the specific differential resistance and dynamical reverse recovery measurements to determine the mean carrier concentration were carried out for different temperatures and forward current densities. The specific differential resistance of the drift layer decreased from 10 mΩcm2 at 80 Acm-2 to 6.6 mΩcm2 at 180 Acm-2, whereas the mean carrie

Abstract:
The paper reports analysis of carrier mobility in a Parallel Gated Junctionless Field Effect Transistor. Fully analytical mathematical models for electron and hole mobilities are developed. The mobility models are developed using empirical relation between mobility and transverse and longitudinal electric field. The Quantum confinement effect has also been considered in the models. In the model electric field dependence on classical and quantum mechanical effects are formulated separately. The total electric field is the summation of the two. The models are compared with Technology Computer-Ai

Abstract:
We investigate the transport properties of charge carriers in disordered organic semiconductors using a model that relates a mobility with charge carriers (not with small polarons) hopping by thermal activation. Considering Miller and Abrahams expression for a hopping rate of a charge carrier between localized states of a Gaussian distributed energies, we employ Monte Carlo simulation methods, and calculate the average mobility of finite charge carriers focusing on a lower density region where the mobility was shown experimentally to be independent of the density. There are Monte Carlo simulat

Abstract:
In this paper, the carrier mobility analytical model in a POFET (Polymer Field Effect Transistor) channel is proposed. The model was developed on the basis of existing models and experimental results. The proposed model is universal because it encompasses the carrier mobility dependence on temperature, electric field and trap density in the POFET channel. The model is comparatively simple, easy for application and gives valuable results. According to the presented model, simulations of mobility as a function of the parameters of interest were performed. The obtained results are shown graphical

A new analytical model for carrier mobility in silicon is presented, which is strongly oriented to CAD and suitable for implementation in device simulators. The effects of the electric field, temperature, and doping concentration are accounted for. In particular, the model unifies the descriptions of majority- and minority-carrier mobility and includes the full temperature dependence. The effects of a high longitudinal field are included in the conventional velocity-saturation form; the doping dependence is also incorporated in the latter.

Background: Applications of two-dimensional (2D) materials in electronic devices require the development of appropriate measuring methods for determining their typical semiconductor parameters, i.e., mobility and carrier lifetime. Among these methods, contactless techniques and mobility extraction methods based on field-effect measurements are of great importance. Results: Here we show a contactless method for determining these parameters in 2D semiconductors that is based on the photomagnetoelectric (PME) effect (also known as the photoelectromagnetic effect).

Organic π-conjugated Donor-Acceptor copolymers are emerging as potential candidate materials for organic field effect transistor (OFET) and organic photovoltaic (OPV) applications. The electron-deficient benzothiadiazole group coupled with an electron-rich oligothiophene to form donor-acceptor copolymers has attracted significant attention. These low optical band gap materials absorb photons in the range of 400-800 nm and exhibit good thermal stability. In particular, poly(benzothiadiazole-sexithiophene) (PBT6) exhibits excellent performance in optoelectronic devices and high thermal stability

Abstract:
Scaling of electronic devices is driven, from the consumption side, by the need for compact electrical products, increase in device speed and from the production side, by lowering of production cost. However, aggressive scaling gives rise, among others, to high gate tunnelling currents in contemporary silicon dioxide (SiO2) based Metal-Oxide- Field Effect Transistors (MOSFETs). SiO2 is therefore expected to be replaced in future technologies with alternative dielectrics. Several dielectrics with high dielectric constants (high-κ) are being studied as candidates for integration into transistors

The experiments suggest that the dominating 1/f noise in the frequency range below 1 kHz is generated within the bulk channel material, bo

Making Education Work for the Poor identifies wealth inequality as the gravest threat to the endangered American Dream. Though studies have clearly illustrated that education is the primary path to upward mobility, today, educational outcomes are more directly determined by wealth than innate ability and exerted effort. This accounting directly contradicts Americans' understanding of the promise the American Dream is supposed to offer: a level playing field and a path towards a more profitable future.

If the carriers populate several energy levels with different mobilities in field direction e.g. manyvalley semiconductors or sub bands in confined systems the energy gain is not the same in these sublevels since it is proportional to the mobility.

Although sources of natural hydrogen have been identified in various parts of the world, it is not possible to estimate at this time the potential of these sources, nor to assess their exploitation capacities without further exploration. Thus, hydrogen is not a primary energy source but should only be considered as an energy carrier.
