Abstract
Two CuInS2 semiconductor samples synthesized from chemical elements with the equiatomic cation ratio (N Cu/N In = 1) and either an excess or stoichiometric sulfur content have been investigated by 63Cu and 115In nuclear magnetic resonance. The spectra were recorded on a Bruker Avance-400 spectrometer at a temperature of 290 K and frequencies of 106.14 MHz (63Cu) and 87.67 MHz (115In). Numerical simulation made it possible to determine the quadrupole coupling constants: 0.34 MHz (63Cu) and 1.1 MHz (115In). For the samples synthesized with excess sulfur (above stoichiometry), distortions are revealed in both the 63Cu and 115In spectra.
