Semiconductor Physics Session 5 P N Junction Diode Pdf P N This chapter introduces the construction, working, characteristics and applications of p n junction diode and other special diodes like zener diode, photodiode, led. Two blocks of pn junction semiconductor material are represented in fig. 1 1; one block is p type material, and the other is n type. the small circles in the p type material represent holes, which are the majority charge carriers in p type.
04 Pn Junction Diode Pdf P N Junction Semiconductors Lecture 19 the p n junction the p n junction is the interface between a p doped and n doped se. iconductors (figure 19.1a). the p n junction is the fundamental building block of semiconductor electronic de vices. The document discusses p n junction diodes. it describes how p type and n type semiconductors are formed by doping silicon or germanium with different impurities. When one side of a single crystal of a semiconductor is doped with donor impurity atoms (diffused impurities with five valance electrons) and the other side of the same crystal with acceptor impurity (diffused impurity with three valance electrons) a p n junction is formed. Physically, diodes are formed by the interface between two regions of oppositely doped semiconductor (i.e., pnjunction) and are thus, structurally, the simplest semiconductor devices used in electronics.

A pn junction provided with copper wire (conductor) connecting leads becomes an electronic device known as a diode. diodes are used in a wide range of applications like rectification, voltage regulation, protection against high voltage and wave shaping. V i schematic diagram p(anode) n(cathode) symbol * a p n junction is useful as a stand alone device (the diode). * it is also an integral part of devices such as transistors, igbts, thyristors, etc. * in integrated circuits, pn junctions are used to provide isolation between devices. The semiconductor’s p side, or positive side, has an excess of holes, whereas the n side, or negative side, has an excess of electrons. the doping process is used to produce the p n junction in a semiconductor. A tunnel diode or esaki diode is a type of semiconductor diode which is capable of very fast operation, well into the microwave frequency region, by using quantum mechanical effects.
