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…
