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

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

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.

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

The continuous downscaling has enforced the device size and oxide thickness to few nanometers. After serving for several decades as an excellent gate oxide layer in complementary metal oxide semiconductor (CMOS) devices, the thickness of SiO2 layer has reached to its theoretical limits. Ultra-thin films of SiO2 can result in severe leakage currents due to direct tunneling as well as maintaining the homogeneity of the layers becomes an additional challenge. The use of a high- (HK) layer can solve these twin concerns of the semiconductor industry, which can also enhance the capacitance due to s

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

In this thesis, based on the use of photonic crystal structures, we propose two filter structures which could be of technical use in photonic applications. The first part is to exploit the transfer matrix method（TMM）to design and simulate the filtering properties of antireflection coating (ARC) on silicon substrate. We have made several analyses on the three-layer and four-layer ARC structures. The ARC filter is desig

Based on numerical simulation, both the MDM SPR sensors with appropriate parameters and the traditional SPR sensors were fabricated. The full width at half maximum of the MDM SPR sensor under angular interrogation was found to be narrower than that of traditional SPR sensor both in numerical simulation and in practice. In addition, a novel MDM SPR sensor featured with the function of self-correction was

Photonic band gaps (PBGs) is most fundamental properties of photonic crystals (PCs). When the frequency of electromagnetic wave falls on photonic band gaps (PBGs), the electromagnetic wave can not propagate in the photonic crystal structure. We use metal materials to design photonic crystal and study their properties. We also calculate the transmission, absorption and reflection of the correspondence with the frequency of the incide

The materials used are Ag, LiF, Au, ITO, and InN. By changing the wavelength of the incident light, the thin film materials and their thicknesses, we can study the optical properties of the surface plasma wave. In Chapter 2, we first study the basic properties of the SPW, including the excitation of SPW, long-range SPW, and the dispersion relation of symmetric structure. The properties such as the resonance angle displace
