Quantum Theories of Solids,the separation in energy between the levels becomes progressively smaller. It is obvious that as . is increased, the computations involved in a solution of the wave equation become less manageable. Simplifying assumptions must be made. There are essentially two approaches to the problem.

p-n Junctions,trons move from n to p, leaving a region of ionised impurities of positive charge behind them. Similarly, holes move from p to n, leaving a negative space charge. Counteracting the diffusion process, there is an electrical field & due to charge separation. The net flux of holes is then given by the expression

Junction Transistors,ns although it is quite simple to extend the concepts to multijunction structures. The punch-through diode and bulk barrier diode (both single carrier devices) were presented for consideration as problems at the end of the chapter.

Donard de Coganics; and he was extremely widely read in the history and philosophy of science, as well. In this connection, I recall the following incident, which is representative. I had been reading René Thom’s ., a heady blend of mathematics, biology, and pre-Socratic philosophy; the experience left me in a sta
