WebExcitonic fractional quantum Hall hierarchy in moiré heterostructures WebApr 19, 2016 · Abstract. In this chapter, we report the observation of the quantum anomalous Hall effect (QAHE) in Cr-doped (Bi,Sb) 2 Te 3 TI thin films grown by MBE method. At zero magnetic field and ultralow temperature (30 mK), the gate-tuned anomalous Hall resistance reaches the predicted quantized value of h / e 2, accompanied by a …
Direct evidence of terahertz emission arising from anomalous Hall effect
WebThe quantized version of the anomalous Hall effect has been predicted to occur in magnetic topological insulators, but the experimental realization has been challenging. Here, we report the observation of the quantum anomalous Hall (QAH) effect in thin films of chromium-doped (Bi,Sb)2Te3, a magnetic topological insulator.
