Toward topological-insulator heterostructures, we grow and characterize the quantum anomalous Hall (QAH) insulator V-doped (Bi,Sb)₂Te₃ (VBST) on migration-enhanced-epitaxy grown ZnTe. The VBST film exhibits the QAH effect at a higher observation temperature than VBST grown directly on InP substrates.
