Conduction mechanism in semiconductors

Specialist area:Electrical engineering
Application:Semiconductor, diode, photoelement, transistor, amplifier

Lecturer:Prof. Dr.-Ing. Hans-Peter Beck
Keywords:Conduction mechanisms:
Conductivity of solid bodies, intrinsic conductivity in germanium, origin of the energy-band model, band model in semiconductors, impurity conduction “N-type” (majority/minority carriers), impurity conduction “P-type” (majority/minority carriers), Hall generator

Simple PN junction:
PN junction, characteristic curves, rectifying effect of a diode, photovoltaic cell, light-emitting diodes

Controlled PN junctions – transistors – thyristors:
Basic principle; transistors – basic properties and circuits; PNP transistor, amplifier; N-channel junction field-effect transistor; MOSFET; thyristors – basic properties, two-transistor model
