The electrically driven Insulator-to-Metal transition
ORAL · Invited
Abstract
Many correlated oxides feature an insulator to metal transition (IMT) with a large change of resistivity. Generally, these transitions can also be induced electrically, a phenomenon known as voltage-triggered IMT [1]. The associated volatile resistive switching has attracted a lot of attention due to potential applications.
Despite the wide interest, the fundamental aspects of this voltage-triggered IMT are not understood. In this talk I will discuss the underlying physics of this phenomenon, including topics such as what governs the characteristic length- and time-scales [1-3]. I will also review the current efforts towards applications, with an emphasis on neuromorphic and probabilistic computing [4].
