PT Journal AU Matthias, BT TI Transition temperatures of superconductors SO Phys. Rev. JI Phys. Rev. PY 1953 BP 874 EP 876 VL 92 IS 4 AB Superconductivity has been found in a number of new compounds between the non-superconducting transition elements and nonmetals such as Si, Ge, and Te. These findings have suggested possible criteria for superconductivity in both elements and compounds. ER
