Understanding Graphene-Perovskite Interactions: From Flake Chemistry to Crystallisation and Solar Cell Performance
Oussama Er-Riyahi, Dorota Biernacka, Yating Guo +7
Graphene-derivatives are widely employed materials to improve bulk and interface properties of metal-halide perovskite devices. Yet the implications of their flake chemistry and in…

Tuning topological phases and exceptional points in a non-Hermitian Rice Mele model beyond nearest neighbors
Carolina Martinez-Strasser, Dario Bercioux, Nico Leumer
Exceptional points are degeneracies characteristic of non-Hermitian operators, where eigenvalues and eigenvectors coalesce, rendering the Hamiltonian defective. We investigate the…
