Abstract Lead‐free halide double perovskites (A 2 B I III X 6 ) with attractive optical and electronic features are considered to be a promising candidate overcome the toxicity stability issues of lead (APbX 3 ). However, their poor absorption profiles limit device performance. Here band edge Cs AgBiBr perovskite near‐infrared range is significantly broadened by developing doped perovskites, (Ag:Cu)BiBr . The partial replacement Ag ions Cu in crystal lattice confirmed X‐ray photoelectron...
Topology is central to understanding and engineering materials that display robust physical phenomena immune imperfections. Different topological phases of matter are characterised by invariants. In energy-conserving (Hermitian) systems, these invariants determined the winding eigenstates in momentum space. non-Hermitian a novel invariant predicted emerge from complex eigenenergies. Here, we directly measure arising exceptional points momentum-resolved spectrum exciton polaritons. These...
