摘要
By using the droplet epitaxy method, we succeed in fabricating the InAs quantum dots (QDs) with the spatial density of 4x10(10)/cm(2) and an average lateral size of 20 nm on GaAs (001) at the droplets deposition temperature of 50 degreesC and subsequent annealing process under As-4 flux. These QDs shows the intense photoluminescence even at room temperature indicating that high-quality InAs QDs can be fabricated by near room temperature droplets deposition and crystallization process by 400 degreesC in situ annealing.
