Topological Phase Transition in Single Crystals of (Cd1−xZnx)3As2

Abstract Single crystals of (Cd1−xZnx)3As2 were synthesized from high-temperature solutions and characterized in terms of their structural and electrical properties. Based on the measurements of resistivity and Hall signals, we revealed a chemical-doping-controlled transition from a three-dimensiona...
