Single crystals of undoped and Au-doped MoS2were grown by the chemical vapor transport method using iodine as a transporting agent. The doping effect of the Au was characterized by temperature-dependent piezoreflectance (PzR) spectroscopy measurements in broad range of temperatures from 25 to 300 K. The temperature dependent PzR spectra revealed prominent features in the vicinity of direct-band-edge excitons for both investigated samples. The energies and broadening parameters of the A and B excitons were determined via a detailed line shape fit of the PzR spectra. We observed that Au doping strongly reduces the splitting between A and B excitons as well as it causes the redshift of observed transitions in relation to the undoped MoS2. The origin of observed excitons was discussed.

ABSTRACTThe vibrational properties of kesterite Cu2ZnSnS4 (CZTS) single crystals were studied by polarization-dependent Raman scattering measurements. The CZTS crystals grown by chemical vapor transport technique using iodine trichloride as a transport agent consist of several mirror-like planes. The detailed analysis of the experimental spectra obtained from different planes allows determining the symmetry assignment of the observed Raman-active modes. The wavenumber values of Raman-active modes are compared with the results of recent theoretical calculations. The presented data are useful for examination of CZTS absorber films applied for solar cells to clarify the existence of structural or phase inhomogeneities.
