Abstract

Highly lattice mismatched (7.8%) GaAs∕GaSbnanowireheterostructures were grown by metal-organic chemical vapor deposition and their detailed structural characteristics were determined by electron microscopy. The facts that (i) no defects have been found in GaSb and its interfaces with GaAs and (ii) the lattice mismatch between GaSb∕GaAs was fully relaxed suggest that the growth of GaSbnanowires is purely governed by the thermodynamics. The authors believe that the low growth rate of GaSbnanowires leads to the equilibrium growth.
