Some Properties of Semiconducting Indium Phosphide

Abstract
Pure polycrystalline samples of indium phosphide have been prepared Point contact experiments have shown useful rectification on both n- and p-type samples, as well as transistor effects with power gains up to 20 times. The infra-red transmission spectrum has been extended to 20 μ, and the effective mass of electrons has been estimated as 0.02m. Previous work on general properties has been revised and extended.
