DEPOSITION, CRYSTALLIZATION AND PHOTOLUMINESCENCE OF a-Si/SiO2 MQW
and a-Si by PECVD were studied under different conditions. a-Si/SiO
2
MQW (multi-quantum well) with high quality were deposited under suitable conditions. It was crystallized by laser annealing and silicon crystalline grain was formed. The grains of Si with size of 3.8nm was found if a-Si layer in the MQW structure was 4nm. Strong photoluminescence with three peaks from the grains was detected at 10K. The wavelengths of the peaks were 810nm
