"Unleashing the Power of Quantum Avalanche: A Game-Changer for Microelectronics and Supercomputing"

A new study on insulator-to-metal transitions, known as resistive switching, has uncovered discrepancies in the traditional Landau-Zener formula and shed light on the quantum mechanics involved. By using computer simulations, researchers found that a relatively small electric field can trigger a collapse of the energy gap between the lower and upper bands of an insulator, allowing electrons to move between them. This insight could have potential applications in microelectronics and neuromorphic computing. The study also suggests that electronic and thermal switching can occur simultaneously, challenging the notion that they are exclusive mechanisms.

Unraveling the Mystery: Nonconductors Transformed into Conductors through 'Quantum Avalanche'

A new study led by University at Buffalo physics professor Jong Han offers insights into the process of resistive switching, where insulators can transition into conductors under an electric field. The study proposes a "quantum avalanche" mechanism, where a relatively small electric field can trigger a collapse of the energy gap between the lower and upper bands of an insulator, allowing electrons to move between them. This finding challenges the long-standing Landau-Zener formula and provides clarity on the debate surrounding insulator-to-metal transitions. The research has implications for microelectronics and could contribute to the development of compact memories and neuromorphic computing technologies.
