Abstract :
Optical properties were studied for In0.52Al0.48 As layers and In0.53Ga0.47As/In0.52 Al0.48As quantum well (QW) structures grown on (111)B InP substrates. It was found that the photoluminescence (PL) spectrum of the InAlAs layers grown on the(111)B InP substrates had a remarkable dependence on the V/III ratio and the growth temperature. The PL peak energy of the InGaAs/InAlAs QWs grown on the (111)B InP substrates showed a red shift compared with those grown on (100) InP substrates. An atomic force microscopy (AFM) observation revealed that the (111)B InGaAs well is thicker than the (100) InGaAs well
