WebMay 18, 2024 · When an electric field is applied across an intrinsic SC, the current conduction takes place by two processes namely; by free electrons and holes. The free electrons are produced due to the breaking up of some covalent bonds by thermal energy. At the same time, holes are created in the covalent bond. WebSep 11, 2024 · A semiconductor in an impure form is known as an extrinsic semiconductor. Basically due to the bad current conduction capability of intrinsic (pure) semiconductors, at room temperature, are not very useful in electronic devices. To make use in electronic devices, the current conduction capability of the intrinsic … show updated ncaa brackets
