Abstract

Due to the basic characteristics of InGaAsSb/AlGaAsSb

based on the calculate lattice constant and energy band of quaternary system through the calculation of structure constants of binary system and ternary system

and analyze the MBE growth parameters and process

we design and grow the InGaAsSb/AlGaAsSb multi-quantum-wells epitaxial materials. The characterization of the layers has been carried out by X-ray double crystal diffraction and photo luminescence. There are several satellite peaks in X-ray double crystal diffraction results which indicate that these prepared InGaAsSb/AlGaAsSb multi-quantum-Wells are with high crystallized quality. The results of PL spectra at the room temperature indicate that the wave length are modulated from 1.6 to 2.28 m

the narrowest PL FWHM is 22 meV.
