Photoluminescence of AlGaAsSb/InGaAsSb multiple quantum well
【摘要】 用固态源MBE技术生长了AlGaAsSb/InGaAsSb多量子阱材料,研究了通过改变多量子阱AlGaAsSb/InGaAsSb中的结构参数,如多量子阱中InGaAsSb的阱宽,AlGaAsSb的垒宽及垒层中Al组分和阱层中的In组分,多量子阱中的阱数等,来提高AlGaAsSb/InGaAsSb多量子阱的PL强度。
【Abstract】 AlGaAsSb/InGaAsSb multiple quantum well material was grown by solid state molecular beam epitaxy (SSMBE). Structural parameters (InGaAsSb well width, AlGaAsSb barrier width, Al fraction in barrier, In fraction in well, well number, etc) were varied to improve the intensity of the photoluminescence.
