Single Crystal Electron Paramagnetic Resonance (EPR) Study of Mn Ions in CuGaS2
نویسنده
چکیده
Single crystals of one mole % Mn doped CuGaS2 (CGS) compound semiconductor were grown by a chemical vapor transport (CVT) technique in a closed system using iodine as a transporting agent. The electron paramagnetic resonance (EPR) of the Mn ions in a CGS single crystal has been studied with an X-band spectrometer recorded at 80 K. The spectroscopic splitting tensor (g), hyperfine constant (A) and zero field splitting (D) parameters were determined using the effective spin Hamiltonian. It turns out that the Mn ions substitute for Ga ion in the sulphur tetrahedron without nearby charge compensation. Keywordssingle crystal; semiconductor; EPR; hyperfine constant
