SEMI-CONDUCTORS (2 films)

Part 1. 21min. Basic physics and theory of hole and electron flow in semi-conductor material as related to the P-N Junction and fundamental principles that apply to junction rectifiers. Part 2. 22min. Fundamentals of transistor low frequency amplification; a brief review of electron and hole flow, P-N Junction characteristics and transistor symbols; build up of amplifying circuits; discussion of common emitter, base and collector circuits; and a detail analysis on the operation of the common emitter and common base circuits.
