Abstract:
Les communications d'appareil à appareil (D2D) sont utiles dans plusieurs domaines, e.g. le déléstage mobile, car elles ne coûtent qu’une fraction du prix d’une communication cellulaire. Dans cette thèse, nous soutenons que la compréhension de l'utilité potentielle derrière les communications directes est la clé pour quantifier les réseaux de contact. Tout d'abord, nous considérons le problème de l'estimation de l'importance d'un nœud dans de grandes topologies dynamiques. Nous proposons une approche nouvelle pour estimer les centralités à partir d'une base de données préétablie, où l'estimati

Abstract:
Two-dimensional (2D) materials have attracted extensive research interest in recent years. Among them, graphene and the semiconducting transition metal dichalcogenides (TMDs) are considered as promising candidates for future device applications due to their unique atomic thickness and outstanding properties. The study on graphene and TMDs has demonstrated great potential to further push the scaling of devices into the sub-10 nanometer regime and enable endless opportunities of novel device architectures for the next generation. In this thesis, crucial challenges facing 2D materials are investi

Abstract:
Rapid and specific diagnostic techniques are needed to expedite specific treatment of bacterial skin infections with narrow-spectrum antibiotics, rather than broad-spectrum. Through this work a device was developed to determine the presence of and species responsible for a bacterial skin infection using differences in Mie scatter spectra created by different bacterial species. A 650 nm LED at five different incident angles is used to illuminate the tissue, with Mie scatter being detected by PIN photodiodes at eight different detection angles.

A nearly ideal spectral response of quantum efficiency at a wide spectrum range provides an evidence for improving light transmission in the window layer and enhancing absorption and carrier generation in absorber.

Abstract:
The nano-contact spin torque oscillator (NC-STO) is an emerging device for highly tunable microwave frequency generation in the range from 0.1 GHz to above 65 GHz with an on-chip footprint on the scale of a few μm. The frequency is inherent to the magnetic material of the NC-STO and is excited by an electrical DC current by means of the spin torque transfer effect. Although the general operation is well understood, more detailed aspects such as a generally nonlinear frequency versus current relationship, mode-jumping and high device-to-device variability represent open questions.

To reduce the bounce a computer-based mathematical model of the system dynamics is developed and optimised; this results in recommended design changes.

Abstract:
Metal oxides are a group of materials that have shown great promise in improving the efficiency of devices based on organic materials through inclusion in the contact structures of such devices. In this work, the deposition technique of spray pyrolysis is developed for use for the deposition of doped zinc oxide films and molybdenum oxide films. Spray pyrolysis is of great interest as a technique for use in the organic electronics field due to its cost, scalability and compatibility with other solution processing techniques. This makes the technique particularly interesting for use in devices i

Abstract:
The GaN system has been of growing interest in the past decade for its potential as a blue-light emitter, and has rapidly achieved commercial importance, but the system also has very attractive properties for high power microwave-frequency transistors, notably formation of a two-dimensional electron gas at the AlGaN/GaN heterointerface, high electron velocity and a large breakdown electric field. The commercialization of such devices is now imminent. Ohmic contacts to GaN and AlGaN/GaN heterostructures are an essential part of the production of all optical and electronic devices from the GaN s

Abstract:
This thesis designed and fabricated various devices that were interfaced to an IC for an active contact lens that notifies the user of an event by detection of an external wireless signal. The contact lens consisted of an embedded antenna providing communication with a 2.4GHz system, as well as inductive charging at an operating frequency of 13.56 MHz. The lens utilized a CBC005 5µAh thin film battery by Cymbet and a manufactured graphene super capacitor as a power source. The custom integrated circuit (IC) was designed using the On Semiconductor CMOS C5 0.6 µm process to manage the battery an

Abstract:
碩士<br>國立臺北科技大學<br>有機高分子研究所<br>99<br>Applications of Aluminum are used in semiconductor device as a connection between layout and also as a good ohmic contact between semiconductor surface and metal layer. Aluminum ohmic contact is related with contact area and silicide density, and it has no CD loss (Critical dimension loss) concern. Wet etch method can provide more high selectivity, high PPH (productive per hour), simple equipment design and low cost compare to plasma etch. So the evaluation of aluminum by wet etch can reduce cost and it increases the output for mass production. This approach
