Title: Optical properties of CuIn{sub 5}Se{sub 8} single crystals

Abstract

Single crystals of the CuIn{sub 5}Se{sub 8} ternary compound are grown by the Bridgman-Stockbarger method (with the vertical layout of the procedure). The composition and structure of the crystals are determined. The spectra of transmittance and photoluminescence are studied in the temperature range from 10 to 300 K. The transmittance spectra and the photoluminescence spectra are used to determine, correspondingly, the band gap and the energy of donor-acceptor transitions in the CuIn{sub 5}Se{sub 8} crystals. The temperature dependences of these parameters are obtained.

  • Using the method of planar crystallization from the melt with deviations from the stoichiometric composition, p-CuIn{sub 3}Se{sub 5} single crystals are grown. The electrical properties of the homogeneous crystals are studied. It is found that the resistivity of the p-CuIn{sub 3}Se{sub 5} crystals depends on the excess Se content in the melt. It is established that the voltaic photosensitivity of the In/CuIn{sub 3}Se{sub 5} structures is enhanced with an increasing excess of Se content in the melt. The energy spectrum and the character of interband transitions in the CuIn{sub 3}Se{sub 5} crystals are discussed. It is concluded that the CuIn{submore » 3}Se{sub 5} ternary compound can be used in high efficiency photoelectric converters of solar radiation.« less
  • A new ternary compound is synthesized for the first time, and bulk CuIn{sub 5}Te{sub 8} single crystals are grown by directed crystallization of near-stoichiometric melt. It is established from X-ray diffraction patterns of grown crystals that they exhibit the structure of imperfect chalcopyrite with parameters of the unit cell of CuIn{sub 5}Te{sub 8}, which were close to those known for the CuInTe{sub 2} ternary compound with the composition index n = 0. First, photosensitive structures are fabricated based on CuIn{sub 5}Te{sub 8} crystals, and photosensitivity spectra are obtained for them; it is shown that it is possible to achieve broadbandmore » photosensitivity under illumination of the barrier side of these crystals. From the analysis of photosensitivity spectra, the character of band-to-band transitions and corresponding energies of these transitions in CuIn{sub 5}Te{sub 8} are determined. This opens up prospects to use this new semiconductor in photoconverters of solar radiation.« less
  • FeIn{sub 2}S{sub 4} and CuIn{sub 5}S{sub 8} compounds and (FeIn{sub 2}S{sub 4}){sub x} · (CuIn{sub 5}S{sub 8}){sub 1–x} alloy single crystals are grown by planar crystallization. It is shown that both of the initial FeIn{sub 2}S{sub 4} and CuIn{sub 5}S{sub 8} compounds and alloys on their basis crystallize with the formation of the cubic spinel structure. It is established that the unit-cell parameter a linearly varies with the composition parameter x. By means of nuclear gamma resonance spectroscopy in the transmission mode of measurements, the local states of iron ions in the alloys are studied. For the single crystals grownmore » in the study, thermal expansion is explored using the dilatometry technique, the thermal-expansion coefficients are determined, and the Debye temperature and rms (root-mean-square) dynamic displacements are calculated.« less
  • Single crystals of the n-CuIn{sub 5}Se{sub 8} compound of hexagonal modification have been grown by direct crystallization from melt. On the basis of the experimental study of its thermal interaction with air oxygen, a method for fabricating new oxide/n-CuIn{sub 5}Se{sub 8} heterojunctions is proposed. Electrical and photoelectric properties of the structures obtained have been investigated. It is shown that the interaction of n-CuIn{sub 5}Se{sub 8} of hexagonal modification with air oxygen makes it possible to obtain heterojunctions with high photosensitivity. The new technology can be used in the design of broadband optical radiation converters based on n-CuIn{sub 5}Se{sub 8} crystals.
  • Single crystals of the CuIn{sub 5}S{sub 8} ternary compound are grown by planar crystallization of the melt (the vertical Bridgman method). The composition and structure of the crystals are established. The specific expansion is measured by the dilatometric technique, and the coefficients of thermal expansion are calculated. From the data, the Debye temperatures ({Theta}{sub D}) and the root-mean-square dynamic displacements of atoms ({radical}(u-bar{sup 2})) in the CuIn{sub 5}S{sub 8} compound are calculated. From the transmittance spectra recorded in the region of the fundamental absorption edge in the temperature range 20 to 300 K, the band gap is determined and itsmore » temperature dependence is constructed.« less
