Abstract
We observed the donor-assisted infrared absorption of Li acceptor in bulk Z nSe. Two kinds of donors, Li-int and/or Ga-Zn, make transition from 1S to 2 S state during photo-excitation of Li acceptor. The transition energies are estimated at 6.3 and 20.2 meV for Li-int and Ga-Zn, respectively. Fano res onances of the valence band state with the simultaneous excited states of a Li acceptor and donors were also observed. (C) 2001 Elsevier Science B.V. All rights reserved.
