Study Of Structural And Electronic Properties Of Intercalated Crtis2 Compound By Density Functional Theory, V. B. Parmar, A. M. Vora

Eurasian Journal of Physics and Functional Materials

In the present paper,we report the structural optimization of intercalated CrTiS₂ compound by using Density Functional Theory (DFT) with Generalized Gradient Approximation (GGA) through Quantum ESPRESSO code. All the computations are carried out by using an ultra soft pseudopotential. The effect of charge transfer from guest 3d transition metal Cr-atom to self-intercalated compound TiS₂ has been studied. In electronic properties, the energy band structure, total density of states (TDOS), partial density of states (PDOS) and Fermi surface have carried out. From the energy band structure, we conclude that the TiS₂ intercalated compound hasa small bandgap while the …
