Abstract:

The results of research structural and phase state, electrophysical properties (resistivity, temperature coefficient of resistance (TCR), strain gauge) of Pt thin films in the range of thicknesses from 7 to 50 nm were presented. Thin films Pt have fcc structure with lattice parameter a 0,390 nm after annealing. The temperature dependences characterized by relative large value of resistivity (ρ ~ 10-6 Ohm m) and relative small value of TCR (β ~ 10-4 K-1) respectively. Strain properties characterized by a wide interval of elastic deformation (more than 1 %), relatively low value of gauge fa

Abstract:

Fuel cells as green and sustainable energy sources are at the heart of future Hydrogen Economy. Current research is focused on creating highly active, stable and low content Pt catalysts to improve fuel cell performance up to standards suitable for commercialization. The development of bimetallic Pt structures is the most promising route for achieving this goal. Besides the lower-noble metal content, combination of Pt with other metal at the nano-scale .can result in enhancement of catalytic activity due to the combination of geometric and electronic effects. The main aim of this work is the d

Bibliography: 104-107.<br>The formation of germanides of platinum has been investigated using both conventional thin films and lateral diffusion couples. The investigation was carried out using such established techniques as XRD, RBS and SEM. Using results from both thin film and lateral diffusion couples, a comparison has been made of the behaviour of Pt-Ge system in parameters such as phase formation sequence, growth kinetics and dominant diffusing species. In their sequential order of formation, three distinct phases, Pt₂Ge, PtGe and PtGe₂, have been identified in thin films in the temperat

Abstract:

With continued shrinking of CMOS technology to reduce the gate delay times, an increase in the resistivity of the metal corresponding to the wire dimension is a concern. This phenomenon of increase in resistivity with decreasing dimension of the thin metallic film or interconnect is known as the "classical size effect". Various theories have been postulated to explain the phenomenon of classical size effect; these theories can be broadly classified as resistivity due to scattering arising from surface and grain boundaries. The total resistivity of metals depends on the electron scattering due

Abstract:

Nanometric thin films are used widely throughout various industries and for various applications. Metallic thin films, specifically, are relied upon extensively in the microelectronics industry, among others. For example, alloy thin films are being investigated for CMOS applications, tungsten films find uses as contacts and diffusion barriers, and copper is used often as interconnect material. Appropriate metrology methods must therefore be used to characterize the physical properties of these films. X-ray scattering experiments are well suited for the investigation of nano-scaled systems,

In Pt/Co/Pt, altering the substrate temperature during deposition of the top Co/Pt bilayer in the range of 100 C to 300 C formed a peak in total interfacial disorder with deposition temperature of 3.3 A at around 250 C.

Abstract:

博士<br>國立成功大學<br>材料科學及工程學系碩博士班<br>99<br>In this research, Ni-Pt thin films were prepared by the electrochemical deposition method. The experiment data were analyzed and presented by electrochemical method (ex: cyclic voltammetry and linear voltammetry), XRD, SEM, ICP-MS, EQCM, WDS, nano-AEM and XAS. The experiments are divided into four part of themes including: (1) the performance of electrochemically amperometric ethanol sensor with Ni-Pt thin films; (2) the electrochemistry and reaction kinetics of sensing ethanol on Ni-Pt thin films; (3) the electrochemical aging effect on the phase transfo

碩士<br>國立成功大學<br>材料科學及工程學系碩博士班<br>94<br>We report in this paper our study on gallium-doped ZnO (GZO) thin films and three-layered thin films, in which a Pt thin film is sandwiched in between two GZO thin films. First of all, GZO thin films were deposited on glass substrates using an RF magnetron sputter deposition method. The optical and electrical properties of GZO thin films with different deposition parameters, including sputtering power, T-S distance, working pressure and oxygen pressure, were investigated. The refractive index and extinction coefficient were obtained by ellipsometry spectr

碩士<br>國立成功大學<br>材料科學及工程學系碩博士班<br>91<br>In this experiment, different composition of Co-Cr alloy targets is prepared by high frequency furnace. The magnetic thin film is coated directly on Si substrate at 300℃ by DC/RF magneto sputter. Various contents of Co-Cr, Co-Cr-Pt, and Co-Cr-Pt-B alloy thin films are prepared. The ratio of elements in the samples is measured by EDS and ICP-MS. The structure is analyzed by XRD. Surface morphology and microstructure is observed by SEM and TEM. Magnetic properties is determined by SQUID. It has been discussed that different Cr contents and adding Pt

Abstract:

碩士<br>國立中央大學<br>物理研究所<br>95<br>The Pt nanoclusters grown from vapour deposition on thin film Al2O3/NiAl(100) have been studied by reflection high energy electron diffraction (RHEED), scanning tunnelling microscopy (STM), and Auger electron spectroscopy (AES). The results show that the Pt nanoclusters (with a mean diameter of 2.25 nm and height of 0.4 nm) are highly crystalline and their structures and phases are significantly affected by the oxide substrate. Structural analysis based on the RHEED patterns indicates that Pt clusters, although with different sizes, have an fcc phase and grow wit
