Non-volatile gated variable resistor based on doped $\ce{La2CuO_{4+\delta}}$ and $\ce{SrTiO3}$ heterostructures

Published: Nov. 1, 2012

Gated variable resistors were manufactured by depositing epitaxial heterostructures of doped $\ce{La2CuO_{4+$\delta$}}$ and $\ce{SrTiO3}$ layers. Their conductance change as function of write current $I$ and write time $t$ followed a simple empirical law of the form $\Delta G/G = C I^A t^B$. This behavior is in agreement with ionic transport that accelerates exponentially with electrical field strength.
