By using the electron-lattice interaction, the phonon frequencies and the phonon's polarization vectors obtained microscopically on the basis of the realistic band structure of 2H–NbS 2 , the electrical and thermal resistivities of 2H–NbS 2 are c

Lattice dynamics of 2H–NbX 2 (X=S, Se) is studied by taking account of electron-lattice interaction derived microscopically on the basis of the realistic tight-binding bands fitted to the first-principles bands of 2H–NbX 2 . Remarkable frequency
