Chemical vapor transport and characterization of MnBi2Se4

ABSTRACTThermodynamic analysis of the vapor phase over ZnGeP2 in Zn-Ge-P-Cl system has been carried out. The analysis showed that this system can be used for the vapor growth of ZnGeP2. Homoepitaxial layers of ZnGeP2 were grown in a closed system using chemical vapor transport. Electrical and photoluminescence properties of the layers were studied, and crystal lattice parameters were measured. Comparison of properties for bulk and vapor grown ZnGeP2 crystals were carried out. It was found that the vapor grown crystals have more perfect structure than the bulk ones, particularly, they have significantly lower vacancy concentration.

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.

The layered FeOCl has been synthesized from Fe2O3 and FeCl3 by chemical vapor transport technique at 380°C., and an intercalation of sodium benzoate into as-synthesized FeOCl was conduct. After the intercalation composites were sonicated for 4 h in butyl alcohol, the colloidal suspension of layered iron oxide nanosheets was obtained. The FeOCl and the intercalation composites were analyzed by powder X-ray diffraction (XRD). Transmission Electron Microscopy (TEM) was also used to characterize the morphologies of the FeO+ Nanosheets. Except to this, the selected area electron diffraction was also performed to examine the iron nanosheets.

We report optimized crystal growth conditions for the quarternary compound AgCrP2S6 by chemical vapor transport. Compositional and structural characterization of the obtained crystals were carried out by means of energy-dispersive X-ray spectroscopy and powder X-ray diffraction. AgCrP2S6 is structurally closely related to the M2P2S6 family, which contains several compounds that are under investigation as 2D magnets. As-grown crystals exhibit a plate-like, layered morphology as well as a hexagonal habitus. AgCrP2S6 crystallizes in monoclinic symmetry in the space group P2/a (No. 13). The successful growth of large high-quality single crystals paves the way for further investigations of low dimensional magnetism and its anisotropies in the future and may further allow for the manufacturing of few-layer (or even monolayer) samples by exfoliation.
