Description
Semiconductors are a class of materials requiring relatively
low energies to excite outer-shell electrons into higher-energy orbitals, thus producing mobile charge carriers in the material.
Devices made from semiconductors are used in practically every aspect of experimental science, including computers, electronics, detector sensors and light sources. In this lecture we will start with an introduction to semiconductor materials, their basic properties and the processes of diffusion and electrical drift. We will then show how these concepts can be used to understand a variety of semiconductor devices, including bipolar diodes, semiconductor detectors, and light-emitting devices.
