Abstract本发明公开了一种低密度InAs量子点的分子束外延生长方法,包括:将GaAs衬底放在样品托上,并引入进样室进行烘烤;烘烤完毕,将GaAs衬底引入制备室,并对GaAs衬底进行除气处理;将除过气的GaAs衬底引入生长室,对GaAs衬底的加热器进行升温,在有As保护的情况下对GaAs衬底进行脱氧;将GaAs衬底的加热器温度降至生长温度,生长GaAs缓冲层,并掺杂Si;生长多对GaAs/AlGaAs分布式布拉格反射镜;降低生长温度,生长低密度量子点;生长InGaAs(Sb)盖层;生长耦合量子点拓展波长;生长掺杂GaAs层;制作上下电极。利用本发明,有效改善量子点发光效率,提高了收集效率以及实现了波长的调控。
