Bipolar Junction Transistors,ich is reverse-biased so that the electric field in the depletion region aids the collection, as in Fig. 4.1(b). If the base region is graded in doping, as in Fig. 4.1(c), the transport of electrons across the base is aided by the electric field there and the frequency response of the transistor is increased.

Insulated Gate Field-Effect-Transistors: MOSFETs, IGFETs and Related Devices,nel depletion type structure the channel is already present (as a result of a shallow .-type diffusion or implant or as a result of interface conditions). This channel can be partially depleted by a negative gate voltage or enhanced by a positive gate voltage.

Solar Cells,ent is five to ten times greater than for generation of power from coal, oil, or nuclear electric power stations. However, there is reasonable hope that in the next few decades photovoltaic costs will be reduced to a level where we will see a significant fraction, say 10–20%, of electric power needs supplied in this way.
