Recently, multicomponent compounds of the AB 2 X 4 type (A is Mn, Fe, Co, or Ni; B is Ga or In; and X is S, Se, or Te) have been of great interest because they can expand the functional possibilities of modern semiconductor electronics [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. These compounds are promising for semiconductor devices of various functional purposes. Photosensitive structures were prepared based on these materials [7,8], heterojunc tions were fabricated on the basis of FeIn 2 Se 4 crystals [9], and nanostructures were synthesized from FeIn 2 S 4 and MnIn 2 S 4 compounds [10-12].New layered semimagnetic MnGaInS 4 semicon ductors were obtained in [13,14]. The electric, photo electric, and optical properties of MnGaInS 4 single crystals were analyzed in [15][16][17][18][19][20].We studied the optical absorption spectra of MnGaInS 4 single crystals in polarized and unpolarized light. MnGaInS 4 single crystals were grown by the Bridgman method. X ray diffraction analysis revealed that they are crystallized into the structure of single packet ZnIn 2 S 4 polytype with the lattice parameters а = 8.31 Å, с = 12.17 Å, and z = 1 (space group Р3m1) [13]. The spectral dependence α(hν) for MnGaInS 4 single crystals was measured in the temperature range of 77-300 K and at photon energies of 2.34-2.80 eV with a system based on an MDR 12 monochromator. Different single crystal samples 10-200 µm thick were investigated.The results of measuring α(hν) in unpolarized light at different temperatures are shown in Fig. 1. It can be seen that the dependence α(hν) becomes blue shifted with a decrease in temperature from 270 to 83 K. In this case, α(hν) in the range of photon energies of 2.37-2.74 eV changes from 2000 to 7000 cm -1 .These results were analyzed according to the theory of indirect and direct optical transitions [21][22][23][24]. The dependence α(hν) can be written aswhere α d , α i , and α b are, respectively, the optical absorption coefficients at direct transitions, at indirect transitions, and under background absorption. The CONDENSED MATTER SPECTROSCOPYAbstract-Optical absorption in MnGaInS 4 single crystals has been studied. Direct and indirect optical tran sitions are found to occur in the range of photon energies of 2.37-2.74 eV and in the temperature range of 83-270 K. The temperature dependence of the band gap has been determined; its temperature coefficients E gd and E gi are -5.06 × 10 -4 and -5.35 × 10 -4 eV/K, respectively. MnGaInS 4 single crystals exhibit anisot ropy in polarized light at the absorption edge; the nature of this anisotropy is explained.
