| Outline of Final Research Achievements |
The CuxAg1-xInS2 crystals were grown by the vertical Bridgman method. The spectroscopic ellipsometry spectra revealed distinct critical points structures. Polarization dependence was observed in the light absorption spectra for AgInS2. Photoreflectance measurements indicate that the lowest bandgap energies show unusual temperature dependence at low temperature. The spin-orbit and crystal-field splitting energies of AgInS2 were determined to be 38 meV and -168 meV at 10 K, respectively.
