Superconducting transition in TlBiTe2 and TlTe compounds

On the basis of zone structure calculation for TlBiTe2 and TlTe it is found that TlBiTe2 is a narrow-gap semiconductor and TlTe is a p-metal. At Tsub(c)=0.19 K TlTe is found to experience the superconducting transition. In TlBiTe2 superconductivity is not observed to occur up to 0.05 K, since there is on possibility of occupying the high density of states zones because they are remote from actual ones. The earlier discovered superconducting transition in TlBiTe2 is inherent in the alien phase of TlTe
