In the energy band diagram
WebThe band structure as shown in this standard diagram contains a tremendous amount of information; at this level it is, e.g., evident that: Si has a band gap of about 1 eV. Si is an indirect semiconductor because the maximum of the valence band (at G) does not coincide with the minimum of the conduction band (to the left of X). WebTo understand how band structure changes relative to the Fermi level in real space, a band structure plot is often first simplified in the form of a band diagram. In a band diagram …
