摘要：

We report resistivity and superconducting transition temperature measurements on ultrathin MoC films (down to 4.0). We find that the critical sheet resistance separating the superconducting and insulating states at T=0 lies in the range 2.8-3.5 k©, which is about one-half of that reported for Bi films. © 1990 The American Physical Society.
