Abstract:

Single crystals of Tungsten Ditelluride WTe2 having a 2D layered structure are grown by chemical vapor transport method using bromine as the transporting agent. The structure and properties of the WTe2 single crystals as well as exfoliated thin film samples were characterized using XRD single crystal and powder X-ray diffraction, EDX, Raman spectroscopy and spectroscopic ellipsometry. The quality of the samples relation to growth conditions is further accessed and possible applications discussed.

Keywords: WTe2 single crystals, 2D layers, synthesis, characterization
