Why is the Valence Band Important in Nanomaterials?
The properties of the valence band significantly influence the behavior of nanomaterials. At the nanoscale, quantum confinement effects can alter the energy levels within the valence band, leading to unique chemical, electrical, and optical properties. For instance, the bandgap in quantum dots can be manipulated by changing the size of the dots, which directly affects their emission and absorption spectra.
