Electric-Pulse-driven Electronic Phase Separation, Insulator-Metal Transition, and Possible Superconductivity in a Mott Insulator.
Advanced Materials (Deerfield Beach, Fla.), 2008•europepmc.org
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 a nanometer-scale electronic phase separation generated
in the bulk material.
