In the energy band diagram
Webband diagram of the p-n junction. Figure 4.4 shows the energy-band diagram of a p-n junction under equilibrium. The distance between the Fermi level and the valence and/or conduction bands does not change in the quasi-neutral regions and is the same as in the isolated n-and p-type semiconductors. WebSep 26, 2024 · With doping and energy band diagrams, this article provides an overview of intrinsic and extrinsic semiconductors. Intrinsic Semiconductor. The definition of an intrinsic semiconductor is a semiconductor that is exceedingly pure. According to the energy band theory, the conductivity of this semiconductor will be zero at ambient temperature.
