Glass-like Electronics in Vanadium Dioxide

Abstract

Functional materials can offer new paradigms for miniaturized and energy-efficient electronics, providing a complementary or even alternative platform to metal-oxide-semiconductors. Here we report on electronically accessible long-lived structural states in Vanadium Dioxide that can offer a scheme for data storage and processing. We show that such states can be electrically manipulated and tracked beyond 10,000 seconds after excitation, exhibiting similar features of glasses, which are beyond the classic metastability in Mott systems. Glass-like electronics can potentially overcome some of the fundamental limitations in conventional metal-oxide-semiconductor electronics, and open avenues for neuromorphic computation and multi-level memories.
