Abstract:

In this PhD thesis, we study properties of stationary transverse magnetic polarized waves in structures built of a Kerr-type nonlinear dielectric layer, metal and linear dielectric layers. Although these waves, called here plasmon-solitons, have been studied for more than 30 years, there is still no experimental confirmation of their existence. The main reason being that, in all the configurations predicted so far, the nonlinear index modification required to observe plasmon-solitons corresponds to light intensities orders of magnitude higher than the damage threshold of typical nonlinear mate

Abstract:

The object of the present research is to design and fabricate metal-dielectric thin film multilayer structures that make use of the nonlinear optical (NLO) response of Ag for efficient nonlinear absorption for sensor protection. These structures employ structural resonances to overcome the challenges of reflection and absorption that limit access to this large NLO response. The research consists of three parts: first, we present a comprehensive analysis of the contributions to the nonlinear optical response of Ag. Second, we present a systematic investigation of the linear optical propertie

Abstract:

A new class of electrodes with nanometer-scale contact spacing can be produced at the edge of patterned metal/insulator/metal this film structures. A key challenge is to produce insulator layers with low leakage current and have pristine metal contacts for controlled molecular contacts. Atomic layer deposition of high quality Al2O3 thin films onto Au electrodes was enabled by surface modification with a self-assembled monolayer of -OH groups that react with a monolayer of trimethylaluminum gas source. Ar ion milling was then used to expose the edge of the Au/dielectric/Au structure for molecul

With increasing demand for nanoscale optical devices, the ability to confine the light on length scales smaller than those allowed by the diffraction limit of light has begun to attract enormous interest. A possible solution to this problem is offered by Plasmonics. Under certain conditions, a metal-dielectric interface supports Surface Plasmons (SPs), i.e. electromagnetic excitations strongly coupled to oscillations of free electrons in the metal. Thanks to these excitations, electromagnetic energy can be confined in a sub-wavelength volume close to the metal surface. This opens up the way f

Abstract:

Organic thin film transistors (TFT) are an attractive option for low cost electronic applications and may be used for active matrix displays and for RFID applications. To extend the range of applications there is a need to develop and optimise the performance of non-volatile memory devices that are compatible with the solution-processing fabrication procedures used in plastic electronics. A possible candidate is an organic TFT incorporating the ferroelectric co-polymer poly(vinylidenefluoride-trifluoroethylene)(P(VDF-TrFE)) as the gate insulator.

Abstract:

Oxide dielectric breakdown is an old problem that has been studied over decades. It causes power dissipations and irreversible damage to the electronic devices. The aggressive downscaling of the device size exponentially increases the leakage current density, which also raises the risk of dielectric breakdown. It has been proposed that point defects, current leakages, impurity diffusions, etc. all contribute to the change of oxide chemical composition and ultimately lead to the dielectric breakdown. However, the conclusive cause and a clear understanding of the entire process of dielectric bre

In this thesis, we have designed and fabricated a new hybrid nanostructure, dielectric-embedded metallic grating, via large patterning nanoimprimt lithog- raphy technique. The plasmonics properties of Fabry-Perot resonance in such device are investigated both experimentally and theoretically. The anticross- ing behavior due to the strong coupling between the surface plasmon polari- tons and Fabry-Perot resonace is obs

Abstract:

We want to study the effect when an alkali material Sr is substituted on rare earth material site site of Nickelate and Cobaltate. The samples are primed by Sol-gel method. The structural analysis of the samples is done by detail Rietveld analysis of XRD data by which represents the samples are in single phase. The granular information and size is surveyed through SEM analysis. The band gap of both Cobaltate and Nickelate is measured by UV Visible spectroscopy technique which shows that the samples are semiconducting in nature. The dielectric measurement of two samples is done to find out diel

Therefore, the purpose of this study is to develop a fast and accurate stochastic solver for extracting 2D and 3D multi metal-dielectric interconnect capacitances. The development of the algorithm in this study is based on the squared-shaped random walk, combing Stop at Interface method proposed by Chang,C.C. et al (originated from Lin,Y,B’s master thesis), the approach of the chance of walking on the interface from document Coz, and the method of numeri

Due to the periodic and chiral structure, the gyroid has been shown to exhibit photonic band gap and circular polarization dependent characteristics. Previous results show that the optical properties of the double gyroid can be tuned by refractive index contrast of the constituent materials or the volume fraction. However, double gyroid structures are mainly studied based on one constituent material, either dielectric or metal. The influence of different material

Non-metal optical head composed of dielectric surface grating on a metallic thin film was proposed. In this thesis, simulation tools and experiments were carried out to prove that non-metal optical head works as metal optical head previously reported. Analyzing the simulation results, surface plasma is shown to play an important role in the directional beaming phenomenon. The main reason for designing non-m

Abstract:

碩士<br>國立清華大學<br>動力機械工程學系<br>95<br>With the increase of need for high-function electronic devices such as DRAM chip, electronic devices are being pushed towards high density, lightweight and miniaturization. To attain the goal, a fine circuit rule and high speed device are generally required. As the line space and width of IC interconnect continue decreasing, the parasitic capacitance and resistance of devices would correspondingly increase and, unfortunately, result in the increase of RC delay. It can be however improved by using copper (Cu) metallization and low dielectric materials. However,

Surface Plasmon Resonance (SPR) is a physical phenomenon which can be described as a result of interactions occurring at metal-dielectric interface between infrared or visible frequency electromagnetic waves and surface charges in the metal. The most useful merit of SPR, being extremely sensitive to the complex refractive index changing near the interface within a distance range from ~10nm to ~100nm, make SPR become an intensively studied and developed bi

Abstract:

Transition metal compounds present a unique class of solids with complex and diverse thermodynamic properties. 3d transition metal oxides exist with a great variety of crystal structures, which are reflected in the richness of their physical properties. The orbital states of 3d electrons are to a large extent responsible for the complex relationship between the electronic properties and crystal structure. This complexity and diversity are the indication of strong interplay between electronic, lattice, orbital and spin degrees of freedom. The magnetic ground states of these oxides depend strong
