Popis: | Laser-induced cooling of the conduction electrons in n-InSb is observed for CO laser photon energies near the bandgap (229–234 meV). This cooling is caused by a new mechanism which we call cold electron photo-injection (CEPI) produced by the simultaneous application of a non-ohmic dc electric field and the CO radiation. The results show that absorption near the bandgap is strongly influenced by two acceptor levels located at ~3 and ~8 meV above the valence band edge. |
