Lorsqu'une structure MOS (Métal Oxyde Semiconducteur) est soumise à une perturbation extérieure (exemple : un fort champ électrique, ou une radiation) il y a génération de défauts dans la couche d'oxyde et à l'interface oxyde-semiconducteur. Si on arrive aisément à mesurer séparément les états d'interface (défauts d'interface Si/SIO2) et les défauts d'oxyde à l'aide des méthodes électriques, il nous est actuellement difficile de séparer entre les différents types de défauts d'oxydes (charge positive, négative et pièges de bords).

Abstract:

This dissertation is focused on understanding heterogeneous metal catalysts supported on oxides using a model catalyst system of SiO2 thin film supported metal nano-clusters. The primary technique applied to this study is scanning tunneling microscopy (STM). The most important constituent of this model catalyst system is the SiO2 thin film, as it must be thin and homogeneous enough to apply electron or ion based surface science techniques as well as STM. Ultra-thin SiO2 films were successfully synthesized on a Mo(112) single crystal. The electronic and geometric structure of the SiO2 thin fil

Abstract:

Porous silicon dioxide thin films were produced via dip-coating and doped with Ag+ by adding AgNO3 to the dipping solution. Nanoparticles were formed within the pores of these films by UV exposure. Nanoparticle formation was confirmed by UV-visible spectroscopy and Transmission Electron Microscopy (TEM). Conductive Atomic Force Microscopy (CAFM) showed that the conductivity of the films decreased upon exposure to UV. This decrease in the conductivity is most likely due to the clustering of charge carriers. Initially, Ag+ ions are attached to negatively charged pore walls in a dense packing net

The samples morphological characterizations are done using XRD and SEM. And electrical characterizations are done using C-V and I-V. XRD and SEM confirmed its amorphous nature.

Poly(allylamine hydrochloride) and negatively charged two-sizes SiO2 nanoparticles are assembled sequentially by using a dip coater. Surface roughness required for superhydrophobicity has been achieved by controlling the dipping time and bilayer number. A transparent superhydrophobic film was finally created by calcinations and surface silanization. The ex

碩士<br>國立雲林科技大學<br>電子與光電工程研究所碩士班<br>100<br>In this study we use simulation to find the effect of the gradient layer, and then we focus on the fabrication of ITO which investigates the effect of parameter for ITO by Radio Frequency Magnetron Sputtering. Finally we combine with SiO2 and Ag contact to complete the double anti-reflection layer. In the simulation we find that it can reduce the reflection of light by insert the gradient layer of (SiO2)x(Si3N4)y between SiO2 and Si3N4 and we can get 7.84% average reflectance. The other way we investigate the effect of parameter for ITO. We find t

Abstract:

LiCoO₂thin films have been grown by pulsed laser deposition on stainless steel and SiO₂/Si substrates. The film deposited at 600°C in an oxygen partial pressure of 100mTorr shows an excellent crystallinity, stoichiometry and no impurity phase present. Microstructure and surface morphology of thin films were examined using a scanning electron microscope. The electrochemical properties of the thin films were studied with cyclic voltammetry and galvanostatic charge-discharge techniques in the potential range 3.0-4.2 V. The initial discharge capacity of the LiCoO2 thin films deposited on the stain

The structural and magnetic properties of the composite films were studied by X-ray diffraction(XRD),transmission electron microscopy(TEM), Vibrating sample magnetometer(VSM),respectively. XRD results have shown that Ta layer consisted of B.C.C. with a＝3.31 A, Co layer consisted of H.C.P. with a＝2.51A,c＝4.05A, and CoO layer consisted of F.C.C. with a＝4.27A.TEM results have shown that the grain size of polycrystalline composite films range from 5 to16nm.

It is known that the degradation and breakdown behaviors of thin oxide are a highly localized phenomenon and unique breakdown event can not be easily detected by using traditional measurement method. Measurement instrument with nanoscale resolution is required to characterize the intrinsic breakdown of thin gate oxide.

碩士<br>國立臺灣大學<br>物理研究所<br>101<br>Pentacene is one of the oligomer conducting materials used in small molecule organic optoelectronic devices, such as organic light-emitting diode (OLED), organic field-effect transistor (OFET), and photovoltaic cell (PV). However, the effects of substrate dominate the molecular orientation of the thin film. For instance, pentacene thin films are deposited on gate dielectrics, e.g., SiO2, where a substrate induced phase of pentacene molecules is in the appropriate charge transport direction for an OFET. Therefore, the effects of substrate can play a dominant role

Experimentally, a MTS micro-force testing machine (Tytron 250) with a probe is adopted for bending test. In the test, bending strength and failure strain decrease as the length of the beam increases. The beam has the following mechanical properties: average bending strength 6.32GPa by front loading and 6.21GPa by back loading, average Young’s moduls 130.15GPa, failure strain 0.0528.
