N2 - Superconductivity was discovered in the narrow-gap semiconductor CsBi 4Te6. A superconducting transition around 4.4 K was observed for p-type samples in temperature-dependent resistivity and magnetic susceptibility data. Stoichiometric CsBi4Te6 is not a superconductor. A remarkably high critical field of ∼10 T was estimated from the field-dependent resistivity data. The strongly anisotropic CsBi 4Te6 system is monoclinic and the first member of a larger homologous series Cs4[Bi2n+4Te3n+6] that exhibits unconventional superconductivity, suggesting that proper doping of the homologous series may create a novel class of superconductors from semiconductors.
