Exploring epitaxial structures for electrically pumped perovskite lasers: a study of CsPb(Br,I)${}_3$ based on the \textit{ab initio} Bethe-Salpeter equation

Małgorzata Wierzbowska, Juan J. Meléndez

Halide perovskites are widely used as components of electronic and optoelectronic devices such as solar cells, light-emitting diodes (LEDs), optically pumped lasers, field-effect t…
