A discrete semiconductor is a material/device that has an electrical conductance between an insulator and a conductor. A discrete semiconductor can conduct electricity but only partially. This component is the foundation for many modern electronic devices. In 1901, Jagadish Chandra Bose invented what he called "cat whiskers", a point-contact semiconductor rectifier used for detecting radio waves.
