Material gain and eight-band k.p description for selected perovskites

Krzysztof Gawarecki, Michał Wiśniewski, Maciej Polak +2

In this work, we present a ready-to-use symmetry invariant expansion form of the eight-band k.p Hamiltonian for inorganic and organic metal halide perovskites (CsPbX${}_3$ and MAPbX$…
