a-Si:H/InSb structures have been fabricated by glow discharge deposition of a-Si on bulk InSb substrates in hydrogen atmosphere. The structure shows interesting switching properties, toggling between a high resistance and a conducting state with OFF to ON resistance ratio of 10(6) at remarkably low threshold voltages of 0.3 V at room temperature. The low threshold voltage for this structure, as compared to the higher switching threshold of about 30 V for other a-Si based structures, has been achieved by the use of InSb as a substrate, capable of high carrier injection.
