Research overview:
A direct transition type compound semiconductor AgGaS2 withthe chalcopyrite structure (band gap for A-valence band:2.73eV) is expected as to be one of the candidate materials fora blue emitting diode. The purpose of the present study is to grow high-quality large single crystals and to evaluate the lattice defects of the crystals by measuring photoluminescence and photoconductivity.
