Vm. Andreev et al., QUANTUM-WELL ALGAAS HETEROSTRUCTURES GROWN BY LOW-TEMPERATURE LIQUID-PHASE EPITAXY, Materials chemistry and physics, 45(2), 1996, pp. 130-135
An investigation of the low-temperature liquid-phase epitaxy (LT LPE)
process at 400-650 degrees C for crystallization of AlGaAs heterostruc
tures with ultrathin (2-100 nm) layers has been carried out. Tn partic
ular, low-threshold quantum-well heterolasers (threshold current densi
ty j(th) as low as 120 A cm(-2)) and high-efficiency solar cells (effi
ciency as high as 24.0-24.7% under AMO conditions at concentration rat
io 20-100x) have been fabricated by LT LPE.
