Enhancement-Type FETs

FETs can be categorized as p-channel or n-charmel depending on which carriers are used and as enhancement-type, which are nonconductive in their normal state, and depletion type, which are conductive in their normal state. We will consider the enhancement-type first. [Pg.423]

Although the two choices each of type (JFET, MOSFET) of channel (n-channel, p-channel) and doping (enhancement, depletion) could yield eight choices, in practice only five main FET types exist ... [Pg.545]

Although polythiophenes are best utilized as solution-processable high-performance p-type semiconductors [102], polyselenophenes are of no use as FET materials because of their insolubility. However, it was recently reported that selenophene-containing copolymers 47-50 could form thin films with a solution-processable method and showed p-channel FET responses with hole mobilities of the order of 10 " -10 cm V s [103]. When the thin films were annealed after spin coating, the mobilities were enhanced by one order of magnitude. [Pg.331]
