Ppt Semiconductors Powerpoint Presentation Free Download Id 9467435 The document provides an overview of semiconductors, explaining their electrical properties and the concepts of p type and n type semiconductors, as well as the structure and functionality of diodes. Silicon is by far the most commonly used semiconductor used in integrated circuits. the valance electrons in ge are in the fourth shell, while in silicon are in third shell closer to the nucleus. this means that the ge valance electrons are at higher levels than in silicon and require a smaller amount of energy to escape from the atom.

All these require high precision and efficient materials processing technologies real materials and their processing particles, lines and rigid bodies vs. real materials material specific properties determine the function and processing details of a material comprehensive knowledge of materials processing requires ~ 5 10 years of learning and practice advantage and role of physics students e valence band filled conduction band empty forbidden region eg > 5ev band gap e conduction band eg < 5ev band gap electron hole e valence band partially filled band insulator semiconductor conductor si: eg = 1.1 ev ge: eg = 0.75 ev gaas: eg = 1.42 ev sio2: eg = 9 ev intrinsic semiconductor carriers come from valence electron excitation doped semiconductor n type p type key: effective control of charge carriers jx b vh ey longitudinal conductance: jx = ex = e(n e p h)ex longitudinal resistivity: = 1 the hall coefficient: if electron is the dominant carrier in the material, then we have: = 1 = (en e) 1, and carrier density: n = (erh) 1, and the mobility: e = rh e conduction band band gap electron valence band si: eg = 1.1 ev, = 1100 nm gaas: eg = 1.4 ev, = 873 nm alas: eg = 2.23 ev, = 556 nm hole h electron hole recombination si: indirect bandgap, ineffective gaas: direct bandgap, effective p n diode p n bipolar transistor p e c b metal semiconductor contacts p p n s d g g junction field effect transistor (jfet) p n n g sio2 depletion region metal oxide semiconductor fet (mosfet) inversion region s d real device structures in ic mosfet bipolar transistor diode n n p metal contacts * * * *. The potential energy of the electron becomes a function of its position (cannot be assumed to be constant (and zero) as was done in the free electron model). the magnitude of the energy gap between two bands is the difference in the potential energy of two electron locations.
