Optical and Structural Properties of 3R-MoS2 Synthesized at High Pressure
The rhombohedral (R3) phase of molybdenum disulfide (MoS2) is synthesized from elemental components at high temperatures and pressures. The crystal structure and lattice constants are determined by full-profile X-ray diffraction analysis of the synthesized powder. Scanning electron microscopy in combination with energy-dispersive X-ray microanalysis confirms the formation of layered crystals with the elemental composition of Mo and S in the ratio of 1 : 2. Luminescence spectra of the 3R-MoS2 bilayer transferred onto a SiO2/Si substrate demonstrate narrow emission lines characteristic of low-defect materials.
