BAND-STRUCTURE AND SUPERCONDUCTIVITY OF BCC TELLURIUM UNDER PRESSURE

We report a theoretical calculation of the band structure and supercon ductivity of Te in the BCC phase under pressure. The energy band struc ture and the effect of pressure on the band structure is obtained by m eans of the linear muffin-tin orbital method. The superconducting tran sition temperature (T(c)) is calculated using McMillan's formula. The calculated value of T(c) of Te in the BCC phase at 27.3 GPa is 7.16 K. Further increase in pressure decreases the T(c) values. The calculate d value of resistivity at 27.3 GPa is 4.37 muOMEGA cm and further incr ease in pressure decreases the resistivity, which is a typical behavio ur of a number of elemental metals under pressure.
