Theoretical Study of a Zigzag Graphene Nanoribbon Field Effect Transistor Hossein Karamitaheri‚ Mahdi Pourfath‚ Neophytos Neophytou‚ Hans Kosina Institute for Microelectronics‚ TU Wien‚ Gusshausstrasse 27-29/E360‚ 1040 Wien‚ Austria E-mail: {karamitaheri | pourfath | neophytou | kosina}@iue.tuwien.ac.at Abstract Graphene nanoribbons with zigzag edges show metallic behavior and are thus considered not appropriate for transistor applications. However‚ we show that by engineering line defects

Semiconductor The diode – A diode is an electronic component which allows electric current to glow in only one direction. Diodes are constructed from semiconductors. The anode is the positive terminal and the cathode the negative terminal. LED= light emitting diode a diode which emits light. Semiconductor materials Silicon is the most commonly used semiconductor in electronics‚ germanium is also used. These elements form a stable crystal lattice‚ with each atom sharing its four outer electrons

1. Introduction Automatic Street Light Control System is a simple and powerful concept‚ which uses transistor as a switch to switch ON and OFF the street light automatically. By using this system manual works are removed. It automatically switches ON lights when the sunlight goes below the visible region of our eyes. It automatically switches OFF lights under illumination by sunlight. This is done by a sensor called Light Dependant Resistor (LDR) which senses the

size‚ high performance‚ reliable device operation‚ and good scalability. Use of thyristor provides a positive regenerative feedback that results in very large bit cell operation margins. The difference is that the four-transistor CMOS latch of a 6T-SRAM is replaced by the PNP-NPN bipolar latch of a single thyristor device‚ which reduces cell area dramatically and enables high-density macros. 2: Need of the technology: There has always existed a fundamental performance-density trade-off between

Electronics Part A (Answer all questions) ECE 1312 Q.1 [10 marks] 1. A PN junction is forward biased when: a. the applied potential causes the N-type material to be more positive than the P-type material b. the applied potential causes the N-type material to be more negative than the P-type material c. both materials are at the

Abstract: The main aim of this assignment is to design a pre amplifier circuit with an NPN transistor to be used in a simple public address (PA) system. The pre amplifier is fed from a microphone that produces an average output voltage of 10 mV rms. The amplifier is to operate over a frequency range of 300 Hz to 5 kHz and should have an adjustable volume control. The expected gain of the amplifier is 100. First we are going to design an amplifier for given specifications‚ model the operation of the

Today’s world is overrun by computers from the small to the big. These include the desktop that is in many homes to the cell phones in your pocket. Even things like your car‚ dishwasher‚ dvd player‚ and even TVs include some form of computers. All this would not be possible without the invention of the integrated circuit or IC. This led to the creation of the Microprocessor or CPU (central processing unit) which acts as the brain of the computer. To better help illustrate the function and need for
