Scaling of the Quantum Anomalous Hall Effect as an Indicator of Axion Electrodynamics

S. Grauer, K. M. Fijalkowski, S. Schreyeck +5

We report on the scaling behavior of V-doped (Bi,Sb)${}_2$Te${}_3$ samples in the quantum anomalous Hall regime for samples of various thickness. While previous quantum anomalous Hall…
