63Cu and 115In NMR study of CuInS2 semiconductor

Two CuInS 2 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 63 Cu and 115 In nuclear magnetic resonance. The spectra were recorded on a Bruker Avance-400 spect...

Description
Summary:Two CuInS 2 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 63 Cu and 115 In 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 ( 63 Cu) and 87.67 MHz ( 115 In). Numerical simulation made it possible to determine the quadrupole coupling constants: 0.34 MHz ( 63 Cu) and 1.1 MHz ( 115 In). For the samples synthesized with excess sulfur (above stoichiometry), distortions are revealed in both the 63 Cu and 115 In spectra.
