Abstract


A multidisciplinary team of end users and suppliers has collaborated to develop a novel yet broadly enabling process for the design, fabrication and assembly of Micro-Opto-Electro-Mechanical Systems (MOEMS). A key goal is to overcome the shortcomings of the polysilicon layer used for fabricating optical components in a conventional surface micromachining process. These shortcomings include the controllability and uniformity of material stress that is a major cause of curvature and deformation in released microstructures. The appr ....etc

ABSTRACT
This paper describes the design and implementation of a Three Phase Power Converter (AC/DC/AC) as a fourth year group project for the Power Electronics and Drives B subject at Victoria University. The system implemented converts a three phase input voltage of 400 Vrms at a power rating of 500 W to DC by using a three phase diode bridge rectifier, and a Capacitive filter which assists in stabilising the output DC voltage produced. After that, the system provides the gate drive signal to a three phase pulse width modulated (PWM) ....etc

Abstract
This paper presents an analytic current model for capacitively coupled Single-Electron Tunneling Transistors (SETTs) that is based on a modified M-state steady-state master equation. Based on this current model we also derive a current noise model for SETT. To validate the proposed models we calculate their characteristics at different device parameters and different operation temperatures and compare them with the corresponding characteristics calculated by the full master equation method. The results indicate that the propos ....etc

Abstract

Field emission (FE) (also known as field electron emission and electron field emission) is emission of electrons induced by an electrostatic field. The most common context is field emission from a solid surface into vacuum. However, field emission can take place from solid or liquid surfaces, into vacuum, air, a fluid, or any non-conducting or weakly conducting dielectric. The field-induced promotion of electrons from the valence to conduction band of semiconductors (the Zener effect) can also be regarded as a form of field emission ....etc

What is a Transistor
A transistor is a solid state semiconductor device which can be used for numerous purposes including signal modulation, signal amplification, voltage stabilization, and many other applications.

Transistors act like a variable valve which, based on its input current (BJT) or input voltage (FET), allow a precise amount of current to flow through it ....etc

Single-Electron Transistor (SET) Process and Device Simulation Using SYSNOPSYS TCAD Tools
Abstract:
Simulation of semiconductor device fabrication and operation is important to the design and manufacture of integrated circuits because it provides insights into complex phenomena that cannot obtained through experimentation or simple analytic models. Process and device simulation is commonly using for the design of new very large scale integration (VLSI) devices and processes. Simulation programs serves as exploratory tools in or ....etc

Abstract
The goal of this paper is to review in brief the basic physics of single-electron devices, as
well as their current and prospective applications. These devices, based on the controllable
transfer of single electrons between small conducting islands, have already enabled several
important scientific experiments. Several other applications of analog single-electron devices in
unique scientific instrumentation and metrology seem quite feasible. On the other hand, the
prospect of silicon transistors being replaced by single- ....etc
