Topological Phase Transition in Single Crystals of $(C{d}_{1-x}Z{n}_x{)}_{3}A{s}_2$

Abstract

Single crystals of $(C{d}_{1-x}Z{n}_x{)}_{3}A{s}_2$ 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 dimensional Dirac semimetal to a semiconductor with a critical point $x_c/sim0.38$. We observed structural transitions from a body-center tetragonal phase to a primary tetragonal phase then back to a body-center tetragonal phase in the solid solutions as well, which are irrelevant to the topological phase transition. This continuously tunable system controlled by chemical doping provides a platform for investigating the topological quantum phase transition of 3D Dirac electrons.
