Band alignment of monolayer CaP, CaAs, BaAs and the role of - orbital interactions in the formation of conduction band minima

Magdalena Laurien, Himanshu Saini, Oleg Rubel

Recently, a number of new two-dimensional (2D) materials based on puckered phosphorene and arsenene have been predicted with moderate band gaps, good absorption properties and carr…

Electronic properties of Pb-I deficient lead halide perovskites

Chao Zheng, Oleg Rubel, Mikaël Kepenekian +2

The electronic structure evolution of deficient halide perovskites with a general formula was investigated using the density functional theory. The foc…

Stability of aziridinium lead iodide perovskite: ring strain and water vulnerability

Kangze Ren, Chao Zheng, Michael A. Brook +1

Recently, an aziridinium lead iodide perovskite was proposed as a possible solar cell absorber material. We investigated the stability of this material using a density-functional t…

Unraveling the water degradation mechanism of CHNHPbI

Chao Zheng, Oleg Rubel

Instability of perovskite photovoltaics is still a topic which is currently under intense debate, especially the role of water environment. Unraveling the mechanism of this instabi…

Bimolecular theory of non-radiative recombination in semiconductors with disorder

Oleg Rubel

The original Shockley-Read-Hall recombination statistics is extended to include recombination of localized excitations. The recombination is treated as a bimolecular process rather…

Exploration of the bright and dark exciton landscape and fine structure of MoS (using GW-BSE)

Hongyu Yu, Magdalena Laurien, Zhenpeng Hu +1

Spectral ordering between dark and bright excitons in transition metal dichalcogenides is of increasing interest for optoelectronic applications. However, little is known about dar…
