Abstract
The results from an in-depth characterization of as-grown and annealed low-temperature GaAs layers deposited at less than 260°C are presented. The layers, amorphous as grown, became crystalline after annealing. The crystallization was documented by several characterization techniques including photoreflectance, Raman spectroscopy, photoluminescence, transmission electron microscopy, and double-crystal x-ray diffraction. The n-type conductivity of the annealed films was exploited for the construction of a diode structure.
