Abstract :
In this paper, we analysed the bulk grown low bandgap III-V antimonides with reduced native defects. We have found out that isoelectronic dopants play an important role in determining residual carrier concentrations by compensating native defect thus affecting electrical-optical properties. The properties of InSb, GaSb and GaInSb crystals with various dopants are discussed.
