Abstract

p-type ZnSe with periodic insertion of ZnTe: Li submonolayers was grown by metalorganic molecular-beam epitaxy. The net acceptor concentration, N-A-N-D, up to 2 x 10(17)-5 x 10(18) cm(-3) was observed. However, under higher Li doping, reduction of the growth rate was observed and the growth direction of the islands on the surface changed from the [0 (1) over bar 1] to [011] direction. This resulted in samples not uniformly doped along the growth direction especially for higher Li doping. This reduction of the growth rate was attributed to the adsorptionof Li to the B steps, and this phenomenon was suppressed by a periodic Zn purge to the growing surface. By this method, we could keep the growth rate constant and succeeded in obtaining samples which are dopeduniformly along the growth direction for higher Li doping. N-A-N-D, up to 4.5 x10(17) cm(-3) was measured in this way. The photoluminescence peaks were blueshifted and discrete peaks were observed with increasing Li doping. This interesting behavior was explained with a ZnTe quantum box model. (C) 1998 American Institute of Physics. [S0021-8979(98)10623-0].
