B. Shenoy, Peter Maksymovych, Sergei V. KalininHysteretic metal–insulator
transitions (MIT) mediated by
ionic dynamics or ferroic phase transitions underpin emergent applications
for nonvolatile memories and logic devices. The vast majority of applications
and studies have explored the MIT coupled to the electric field or
temperarture. Here, we argue that MIT coupled to ionic dynamics should
be controlled by mechanical stimuli, the behavior we refer to as the
piezochemical effect. We verify this effect experimentally and demonstrate
that it allows both studying materials physics and enabling novel
data storage technologies with mechanical writing and current-based
readout.
