Phys. Rev. B 64, 060504(R) (2001) [4 pages]True superconductivity in a two-dimensional superconducting-insulating system
We present results on disordered amorphous films which are expected to undergo a field-tuned superconductor-insulator transition. Based on resistance and I-V characteristics, we find evidence of a low field metal-to-superconductor transition. This transition is characterized by a rapid drop in resistance and discontinuities in the I-V curves. The metallic phase just above the transition seems to be an unusual, non-Fermi metal and the superconducting phase seems to be a true zero resistance state. © 2001 The American Physical Society URL:
