Through first-principles structure search calculations, we have identified ten hitherto unknown two-dimensional (2D) Janus-wrinkled TMTe monolayers (TM = Ni, Pd, Pt, Co, Rh, Ir, Fe, Ru, Os, and Hf) by screening 3d, 4d, and 5d transition metal atoms. These monolayers exhibit high stability and metallic conductivity. Among the discovered materials, the 2D PdTe (η
