Semiconductor Physics (6 Parts)

Synopsis

Part 1: Insulators, conductors and semi-conductors are compared and the structure of pure germanium. The concept of electrons and holes and the effects of temperature and electric fields on their movements.
Part 2: The formation of the N- and P- type crystals by the induction of donor and acceptor atoms into the pure semi-conductor crystal. The difference between the minority and majority charge carriers. Conduction in N- and P- type materials.
Part 3: How the formation of a barrier region due to majority carrier diffusion leads to an equilibrium state.
Part 4: The effects of forward and reverse biasing voltages on the barrier region and the action of the junction as a rectifier.
Part 5: The behaviour of a two-junction (P-N-P) semiconductor device and the necessity for a thin base region, concluding with an explanation of the amplifying action of a transistor.
Part 6: A review of the principles of operation of the more common devices now in use, based on the principle that all semiconductor devices are made up of layers or zones of intrinsic and doped materials. First, single layer devices, such as the thermistor and photoconductive cell. Then other layers are added to build up the story for more complex devices such as the field-effect transistor, thyristor and, finally, integrated circuits. In all, eleven different devices are noted, shown using animation techniques.
