Topological Anderson Insulator in Cation-Disordered Cu₂ZnSnS₄

Nanomaterials, 2021
We present the first candidate for the realization of a disorder-induced Topological Anderson Insulator in a real material system. High-energy reactive mechanical alloying produces a polymorph of Cu2ZnSnS4 with high cation disorder.
