The PN Junction Diode George W. Neudeck
Publisher: Prentice Hall

Important Points ( Summary ) on PN Junction ( Diode ). Introduction to PN junction diode. View the complete course: http://ocw.mit.edu/2-57S12 Instructor: Gang Chen. For when we doped it with impurities we produced negatively (N-type) and positively (P-type) charged material. Conductors allow the flow of electrons where as the insulators doesn't allow the flow. Bringing the N and the P together gave us the PN junction. A PN junction diode is an electrical device that allow current to move through it in one direction with far greater ease than in the other. Giving us the diode, transistor and integrated circuit. Reverse Bias - The voltage potential is connected negative, (-ve) to the P-type material and positive, (+ve) to the N-type material across the diode which has the effect of Increasing the PN-junction width. As we know metals are classified into 3 types they are : conductors,insulators and semiconductors. PN Junction under Open Circuit ( Zero Bias ) condition : Potential Barrier consists of only immobile ions , positive ions on n-side and negative ions on p-side. MIT 2.57 Nano-to-Micro Transport Processes, Spring 2012. P-N Junction Diode Problem HELP in Engineering, Comp Sci, & Technology Homework is being discussed at Physics Forums. The effect described in the previous tutorial is achieved without any external voltage being applied to the actual PN junction resulting in the junction being in a state of equilibrium. If p-type semiconductor and n-type semiconductor of a diode are equally doped, and if the diode is forward biased, then holes will move toward the.
