Descripción del proyecto
Una nueva forma de abordar la disipación de energía
En un mundo plagado de los dispositivos electrónicos, la disipación de energía se perfila como un problema crítico. La pérdida de energía causada por el transporte de cargas no sólo dificulta el rendimiento de la electrónica convencional y la espintrónica, sino que también contribuye al consumo global de energía. En este contexto, el proyecto INSULATRONICS, financiado con fondos europeos, aprovechará los aislantes antiferromagnéticos y ferromagnéticos para eludir las pérdidas de energía asociadas al transporte de cargas. Mediante el uso de técnicas innovadoras como los pares de transferencia de espín y el bombeo de espín, los investigadores se esforzarán por reducir drásticamente el consumo energético. El éxito de esta iniciativa podría abrir la vía a un futuro de osciladores, dispositivos lógicos, memorias y procesamiento cuántico de gran eficacia. ¡Sigue de cerca los últimos avances para conocer cómo los científicos están reescribiendo las reglas tecnológicas en materia de eficiencia energética!
Objetivo
The proposal aims to facilitate a revolution of information and communication technologies by controlling electric signals with antiferromagnetic insulators and ferromagnetic insulators. We recently discovered that antiferromagnets can be active components in spintronics devices despite their lack of a macroscopic magnetic moment, and even when they are insulating.
Conventional electronics- and spintronics-based logic and memory devices, interconnects, and microwave oscillators are based on (spin-polarized) charge transport, which inherently dissipates power due to ohmic losses. The research proposed seeks to determine the extents to which “Insulatronics” has the potential to control the electric and thermal signal generation, transmission, and detection in more power-efficient ways.
Insulatronics is profoundly different because there are no moving charges involved so the power reduction is significant. We hope to establish the extents to which spin-waves and coherent magnons in antiferromagnetic insulators and ferromagnetic insulators can be strongly coupled to electric and thermal currents in adjacent conductors and utilize this coupling to control electric signals. The coupling will be facilitated by spin-transfer torques and spin-pumping – a technique we pioneered – as well as spin-orbit torques and its reciprocal process of charge-pumping.
The core of this project focuses on the theoretical and fundamental challenges facing Insulatronics. Beyond the duration of the project, if we are successful, the use of spin signals in insulators with extremely low power dissipation may enable superior low-power technologies such as oscillators, logic devices, interconnects, non-volatile random access memories, and perhaps even quantum information processing.
