Influence of mutual drag of light and heavy holes on conductivity of p-silicon and p-germanium
Conductivity of p-Si and p-Ge is considered for the two-band model with due regard for mutual drag of light and heavy holes. It is shown that for small and moderate temperatures this drag significantly diminishes the drift velocity of light holes and, as a result, the whole conductivity of crysta...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | Conductivity of p-Si and p-Ge is considered for the two-band model with due
regard for mutual drag of light and heavy holes. It is shown that for small and moderate
temperatures this drag significantly diminishes the drift velocity of light holes and, as a
result, the whole conductivity of crystal. The drag effect considered here appears also in
the form of non-monotonous dependences of conductivity on temperature and carrier
concentration. |
