Paper Abstract

Self-organized InP quantum dots having a staggered band lineup are formed in a GaAs matrix by MOCVD. Experimental results of photoluminescence show that the growth behaviors are different when the growth is carried out a different temperatures. Thicker and more smooth wetting layer are evident if the InP is grown at 600 degrees C. For the samples of InP grown at 490 degrees C, besides a weak PL peak resulting from the wetting layer, a strong PL peak located at 986 nm is observed. The luminescence can be attributed to radiative recombination of 0D electrons located in the InP dots and holes located in the surrounding regions. State filling of the 0D electrons is also observed for the type-II quantum dots.
