Microstructural and Nanostructural Characteristics of MSe₂ (M= Nb, Mo, Ta and W) Single Crystals

Abstract:

The single crystals of MSe₂ (M = Nb, Mo, Ta and W) were grown through vapour phase by screw dislocation mechanism. The development of stresses by variation in high temperature of the dual zones involved, resulting into slip lines and vapour inclusion, might possibly lead to generation of favourable screw dislocation sites. The morphology of as grown crystals has been studied by TEM. From this analysis, the general rule that nanoparticles of compounds, crystallizing in layered structures tend to form closed shapes. The formation of closed shapes reduces the number of dangling bonds on the periphery of the layers.
