Energy band diagrams

WebJul 2, 2024 · What is an energy band diagram? In solid-state physics of semiconductors, a band diagram is a diagram plotting various key electron energy levels (Fermi level and nearby energy band edges) as a function of some spatial dimension, which is often denoted x. A band diagram should not be confused with a band structure plot. Web1) Energy band diagrams provide a qualitative understanding of how MOSFETs operate. 23 . 2) MOSFETs are barrier controlled devices – the drain current is controlled by the height of an energy barrier between the source and channel. Lundstrom: 2024 3) In a well-designed transistor, the height of the energy
