InSb-GaAs p-n, p-p, and n-n heterojunctions prepared by molecular beam epitaxy have been characterized using current-voltage and capacitance-voltage measurements. All the junctions exhibit excellent rectifying characteristics. Despite a 14.6% lattice mismatch, excellent diode characteristics with ideality factors as small as 1.04 and low leakage currents are observed. From capacitance-voltage measurements, the valence band discontinuity of InSb-GaAs junction is determined to be between 0.50 and 0.64 eV.
