Semiconductor
A semiconductor is a material whose electronic band structure permits controlled charge conduction, modulated by factors such as impurity doping, temperature, and applied electric fields.
Overview
A semiconductor’s energy bands and band gap shape the behaviour of electrons and holes. Doping, applied voltage, temperature, and light can change carrier populations and motion. Junctions and controlled carrier transport make possible rectification, switching, amplification, and light detection, forming the basis of diodes, transistors, and integrated circuits.
Why it matters
Controllable semiconducting properties enabled solid-state switching, serving as the physical medium for integrated circuits and discrete components. Device architectures derived from semiconductor junctions also support optoelectronic detection, biomedical sensing arrays, and power electronics.
