Abstract

We observed the donor-assisted infrared absorption of Li acceptor in bulk ZnSe. Two kinds of donors, Liintand/or GaZn, make transition from 1S to 2S state during photo-excitation of Li acceptor. The transition energies are estimated at 6.3 and 20.2meV for Liintand GaZn, respectively. Fano resonances of the valence band state with the simultaneous excited states of a Li acceptor and donors were also observed. © 2001 Elsevier Science B.V.
