Semiconductors work by controlling the flow of electrical current through the movement of charge carriers (electrons and holes). The conductivity of a semiconductor can be modified by:
BJTs use both electron and hole currents. They consist of three layers (NPN or PNP) named the Emitter, Base, and Collector. A small current at the base controls a much larger current between the collector and emitter. Field-Effect Transistors (FETs) semiconductors a comprehensive guide pdf
A semiconductor is a material with electrical conductivity between that of a conductor (like copper) and an insulator (like glass). This intermediate property allows semiconductors to act as precise electrical switches. Key Properties Semiconductors work by controlling the flow of electrical
