Abstract
Optical measurements and Transmission Electron Microscopy (TEM) were performed on Low Temperature (LT)-AlInAs layers grown by MBE at 400/spl deg/C and compared with AlInAs grown at 530/spl deg/C. An anisotropic composition modulation is observed along the [1-10] direction for the low temperature samples. We studied the effects of the V-III BEP ratio on this modulation to explain the LT-AlInAs optical properties.
