Experimental evidence of a nonvolatile electric-pulse-induced insulator-to-metal transition and possible superconductivity in the Mott insulator GaTa4 Se8 is reported. Scanning tunneling microscopy experiments show that this unconventional response of the system to short electric pulses arises from

We have studied the effects of disorder in a series of Sn films quench-condensed onto cryogenically cooled substrates. We find a simple scaling of the conductivity with film thickness r ~ (d -de)', with v ~ 0.85, and a metal-insulator transition near dc~40-50A. The superconducting transition tempera
