A. Orth et al., ROOM-TEMPERATURE STIMULATED-EMISSION OF OPTICALLY PUMPED GAAS ALAS QUANTUM WIRES GROWN ON (311)A-ORIENTED SUBSTRATES, Applied physics letters, 64(25), 1994, pp. 3443-3445
Stimulated emission of optically pumped GaAs/AlAs quantum wires direct
ly grown on (311)A-oriented GaAs substrates has been observed at 77 K
and room temperature. A significant reduction of the threshold excitat
ion energy density for stimulated emission at room temperature could b
e measured in comparison to a two-dimensional reference sample as well
as a reduction of the temperature sensitivity of the threshold.
