Capacitive Scheme to Detect the Topological Magnetoelectric Effect
Chao Lei, Perry T. Mahon, C. M. Canali, Allan H. MacDonald · Physical Review Letters · 2024
The topological magnetoelectric effect (TME) is a defining property of three-dimensional Z_{2} topological insulators that was predicted on theoretical grounds more than a decade ago, but has still not been directly measured. In this Letter we propose a strategy for direct measurement of the TME and discuss the precision of the effect in real devices with charge and spin disorder.
