Different Types of Field-Effect Transistors - Theory and Applications
Modulation-doped semiconductor nanostructures exhibit extraordinary electrical and optical properties that are quantum mechanical in nature. The heart of such structures lies in the heterojunction of two epitaxially grown semiconductors with different band gaps. Quantum confinement in this heterojunction is a phenomenon that leads to the quantization of the conduction and the valence band into discrete subbands. The spacing between these quantized bands is a very important parameter that hasdoi:10.5772/intechopen.68374 fatcat:xxtyubck7jandmyyiuopzr3tea
