Abstract

Hg₃In₂Te₆ material belongs to defect semiconductor group with concentration of stoichiometric vacancies up to 10²¹cm^-3, determining its unusual physical properties. In this paper we present the results proving the possibility to use this material for several types of high-efficient photonic structures, including self-calibrating photodiodes, high-speed photodiodes, multielement photodiodes with improved sensitivity and optical filters for spectral ranges 2-28μm. Performed photoconductivity measurements confirmed high photosensitivity of the material in wide spectral ranges of λ=0.35-1.85 μm, covering spectral sensitivity areas of CdS, CdSe, GaAs, Si and Ge. In comparison with these semiconductors, Hg₃In₂Te₆ has the lowest melting point (983K) making it possible to decrease energy consumption necessary for its synthesis. The experimental results also prove high quantum efficiency of the photoconductivity of Hg₃In₂Te₆ for hν = 0.74 - 3.5 eV. Mercury indium telluride is an ideal material for surface-barrier structures and hetero-junctions, due to low density of surface states and insensitivity to absorption of atmospheric oxygen.
