Theoretical work on Ag 3 AuSe 2 and Ag 3 AuTe 2 pre-dicted narrow and direct gaps at the Γ point. Recent density functional theory (DFT) calculations examined their potential applications in dark matter detection and highlighted the tunable band gaps through strain application. 17 Simulated band structures with reduced lattice parameters demonstrated gap-opening for Ag 3 AuSe 2 and gap-closing for Ag 3 AuTe 2 . 17 Specifically, a full gap closure was predicted at -4% strain for Ag 3 AuTe 2 . 17 Our recent DFT simulations using the Perdew-Burke-Ernzerhof (PBE) functional predicted zero gap for the selenide at 3% tensile strain. These findings suggest that alloying Ag 3 AuSe 2 and Ag 3 AuTe 2 may induce gap-narrowing and potentially metallic behavior at an intermediate strain between 3%-strained Ag 3 AuSe 2 and -4%-strained Ag 3 AuTe 2 .
