چکیده انگلیسی
Using the full potential linearized augmented plane wave (FP-LAPW) method we present the structural and electronic properties of Tellurium in the BCC phase at high pressure. Apart from the electronic band structure in the BCC phase, the density of states (DOS) and the Fermi energies (EF) at various pressures are calculated. The equilibrium lattice constant, the phase transition pressure, the bulk modulus and its pressure derivative were found to be in good agreement with the experiment. Further, we have also calculated the electronic specific heat coefficient, which decreases with an increase in pressure.
