BASIC DIODE ELECTRONICS INTRODUCTION TO DIODES The p-n Junction The p-n junction is a homojunction between a p-type and an n-type semiconductor. It acts as a diode‚ which can serve in electronics as a rectifier‚ logic gate‚ voltage regulator (Zener diode)‚ switching or tuner (varactor diode); and in optoelectronics as a light-emitting diode (LED)‚ laser diode‚ photodetector‚ or solar cell. In a relatively simplified view of semiconductor materials‚ we can envision a semiconductor as having two

Electronics Essay Naturally‚ our day to day lives evolve alongside the progression of technology. Some claim that technology has educational benefits‚ yet others believe that technology creates more problems than it diminishes. Although technology allows children to connect to others with ease‚ its negatives still outweigh its positives in the domain of school. Before adapting completely to this new world of technology‚ schools must consider the negative side of technology‚ including its useless

Electronic Gadgets Like Apple iPod - A Boon or Bane It has become a necessity. But like everything in universe‚ electronic gadgets too have two sides to them. I am a house wife. I remember very clearly that evening when my husband came home‚ beaming from ear to ear. He had got a hefty refund on filing his income tax return. And my first reaction was - buy me a washing machine. And I was on cloud nine when my first ever washing machine was delivered. Because I must confess that I hate washing even

In 1965‚ Dr. Gordon Moore working as the Director of R&D for Fairchild Semiconductor published a paper titled “Cramming more components onto integrated circuits”. In his paper‚ he discusses the future of electronics and how these “integrated circuits will lead to such wonders as home computers—or at least terminals connected to a central computer—automatic controls for automobiles‚ and personal portable communications equipment”. He also discusses how the rate in which the number of transistors

ELECTRONIC DICE . TO CONSTRUCT AN ELECTRONIC DICE USING LEDS . BACKGROUND: LED’s History The first known report of a light-emitting solid-state diode was made in 1907 by the British experimenter H. J. Round. However‚ no practical use was made of the discovery for several decades. Independently‚ Oleg Vladimirovich Losev published "Luminous carborundum [[silicon carbide]] detector and

PROJECT IN T.L.E Electronic Components Diodes a diode is a two-terminal electronic component with asymmetric conductance‚ it has low (ideally zero) resistance to current flow in one direction‚ and high (ideally infinite) resistance in the other. A semiconductor diode‚ the most common type today‚ is a crystalline piece of semiconductor material with a p–n junction connected to two electrical terminals. A vacuum tube diode has two electrodes‚ a plate (anode)

Bill to Mandate Electronic Textbooks: I am senator Slover and I stand firmly as affirmation on the bill to mandate electronic textbooks. Electronic textbooks will be the answer to economic struggles in schools all across California. Not only will this action cut down expenses on paper‚ textbooks‚ and the fees for missing textbooks‚ but it will help make money for other departments of education. A study‚ by ALA.org‚ comparing prices of textbooks and an e-book shows that a textbook is approximately
