Spin-Polarized Electronic Structure and Chemical Bonding Data for 2,500+ Halide Double Perovskites
Luc Walterbos, Alex McEwan, Ravindra Shinde +2
Halide double perovskites (ABB'X) are a long-known class of materials that has recently been rediscovered for diverse applications, including photovoltaics, photocatalysis,…
Intra- and Interlayer Excitonic Fine Structure of the Two-Dimensional Perovskite (PEA)PbI
Patrick Grenzer, Fabian Lie, Klaus H. Eckstein +2
Two-dimensional halide perovskites host strongly bound excitons whose fine structure controls polarization selection rules and radiative recombination, yet several spectral feature…
Controlling Excitons in Quasi-1D Perovskites by Dielectric Screening and Connectivity
Kostas Fykouras, Linn Leppert
Reducing the dimensionality of metal-halide perovskites enhances quantum and dielectric confinement, enabling tunable excitonic properties. In one dimension, the arrangement of met…
Structural Distortions Control Scaling of Exciton Binding Energies in Two-Dimensional Ag/Bi Double Perovskites
Pierre Lechifflart, Raisa-Ioana Biega, Linn Leppert
Three-dimensional metal halide double perovskites such as CsAgBiBr exhibit pronounced excitonic effects due to their anisotropic electronic structure and chemical localizat…
