What is semiconductor ? Distinguish between intrinsic and extrinsic semiconductors ? Semiconductor – A semiconductor is a solid whose electrical conductivity lies between the very high conductivity of metals and very low conductivity of insulators . The most commonly known semiconductors are Germanium (Ge) and Silicon (Si). Semiconductors are of two types – i) intrinsic … Continue reading ELECTRONICS | p- type and n- type semiconductors | Biasing of a p-n junction diode
