Chemical Mapping of Excitons in Halide Double Perovskites
Raisa-Ioana Biega, Yinan Chen, Marina R. Filip +1
Halide double perovskites are an emerging class of semiconductors with tremendous chemical and electronic diversity. While their bandstructure features can be understood from front…
Dynamic Distortions of Quasi-2D Ruddlesden-Popper Perovskites at Elevated Temperatures: Influence on Thermal and Electronic Properties
Raisa-Ioana Biega, Menno Bokdam, Kai Herrmann +5
Ruddlesden-Popper hybrid halide perovskite are quasi-two-dimensional materials with a layered structure and structural dynamics that are determined by the interplay between the org…
Halogen Vacancy Migration at Surfaces of CsPbBr Perovskites: Insights from Density Functional Theory
Raisa-Ioana Biega, Linn Leppert
Migration of halogen vacancies is one of the primary sources of phase segregation and material degradation in lead-halide perovskites. Here we use first principles density function…
Chemically-Localized Resonant Excitons in Silver-Pnictogen Halide Double Perovskites
Raisa-Ioana Biega, Marina R. Filip, Linn Leppert +1
Halide double perovskites with alternating silver and pnictogen cations are an emerging family of photoabsorber materials with robust stability and band gaps in the visible range.…
