How Do Material Properties Affect Charge Transport?
At the nanoscale, material properties such as band structure, electron-phonon interactions, and defect states play a crucial role in determining charge transport behavior. For instance:
- Bandgap: The energy difference between the valence band and the conduction band affects how easily electrons can be excited to conduct electricity. - Electron-phonon interactions: These interactions can lead to scattering events that impede charge transport. - Defects and impurities: These can trap charge carriers, reducing mobility and increasing resistance.
