摘要
By using a home-made GSMBE system, high quality In0.53Ga0.47As/InP quantum wells having different well widths (1-18nm) and lattice-matched to (001) InP substrate were achieved. Sharp and intense photoluminescence (PL) peaks for each well can well resolved in the 10K PL spectra. For wells larger than 6nm, the exciton energies are in good agreement with those of calculation. For wells narrower than 4nm, the line widths at 10K are bellow the theoretical values of line width broadening due to one monolayer interface fluctuation, showing that the interface fluctuation of our sample is within one monolayer.
