Next-generation low-power electronics, wireless technologies, and the Internet of Things (IoT) require diode devices that can operate efficiently at high frequencies, with low power input and minimal energy loss—capabilities that remain challenging for conventional diode systems. This project focuses on a new class of materials called quantum diodic magnets (QuDiM), which host “quantum dipoles”—dipolar distributions of quantum wavefunction properties that enable current rectification, where electric current flows more easily in one direction than the other, a defining characteristic of diode function.

Unlike traditional diode materials, QuDiM systems can operate at very high frequencies and low power with minimal energy loss. Importantly, their performance is resilient to impurities and thermal fluctuations. This intrinsic robustness reduces the need for ultra-clean materials, simplifies device design, and makes these systems potentially suitable for diverse environments. To accelerate progress in this emerging field, the research will build an integrated discovery pipeline linking theory, computation, synthesis, and experimental characterization. In parallel, this project will promote interdisciplinary education and open science by developing teaching modules that introduce students to computational, data-driven, and AI-based approaches in quantum materials research.
