Fermi level for p type semiconductor
WebWhat is Fermi Level in Semiconductors? Fermi level (denoted by EF) is present between the valence and conduction bands. It is the highest occupied molecular orbital at absolute zero. The charge carriers in this state have their own quantum states and generally do not interact with each other. WebAug 26, 2024 · We consider a device made of an intrinsic (undoped) p -type semiconductor with a fully filled valence band. The Fermi energy lies in the gap close to the edge of the valence band, as shown in Figure 2 a. In conventions leading to Equation ( 6 ), the Fermi energy corresponds to the upper edge of the valence band.
