In this work, we have carried out an extensive TEM investigation of misfit dislocations and strain relaxation in Sb-based III-V epitaxial layers on the GaAs and GaP substrates. On GaAs, we have investigated the influence of AlSb interlayer thickness and substrate surface treatment on the strain relaxation and threading dislocation density inside GaSb layers. Similarly, we studied the growth parameters, such as substrate surface treatment, growth rate, and growth temperature on the strain relaxation of 10 MLs GaSb on GaP. With the optimized GaSb buffer layers (600 nm), high mobility AlSb/InAs hetero-structures with room temperature mobility of 30000 cm2V-1s-1 (25500 cm2V-1s-1) on GaAs (GaP) substrates have been achieved. A growth mode depend...
