Non-uniform sampling schemes of the Brillouin zone for many-electron perturbation-theory calculations in reduced dimensionality
Felipe H. da Jornada, Diana Y. Qiu, Steven G. Louie
First principles calculations based on many-electron perturbation theory methods, such as the \textit{ab initio} GW and GW plus Bethe-Salpeter equation (GW-BSE) approach, are relia…
Screening and Many-Body Effects in Two-Dimensional Crystals: Monolayer MoS
Diana Y. Qiu, Felipe H. da Jornada, Steven G. Louie
We present a systematic study of the variables affecting the electronic and optical properties of two-dimensional(2D) crystals within \textit{ab initio} GW and GW plus Bethe Salpet…
Direct Observation of Layer-Dependent Electronic Structure in Phosphorene
Likai Li, Jonghwan Kim, Chenhao Jin +14
Phosphorene, a single atomic layer of black phosphorus, has recently emerged as a new twodimensional (2D) material that holds promise for electronic and photonic technology. Here w…
