Electrophoretic-like Gating Used To Control Metal–Insulator Transitions in Electronically Phase Separated Manganite Wires
Electronically
phase separated manganite wires are found to exhibit
controllable metal–insulator transitions under local electric
fields. The switching characteristics are shown to be fully reversible,
polarity independent, and highly resistant to thermal breakdown caused
by repeated cycling. It is further demonstrated that multiple discrete
resistive states can be accessed in a single wire. The results conform
to a phenomenological model in which the inherent nanoscale insulating
and metallic domains are rearranged through electrophoretic-like processes
to open and close percolation channels
