TL;DR: In this paper, the authors employ both theory and experiment to assess the PV relevant properties of SnS and clarify on whether SnS has an indirect or direct band gap and what is the minority carrier effective mass as a function of the film orientation.

TL;DR: Theoretical investigations of doping of several wide-gap materials suggest a number of rather general, practical "doping principles" that may help guide experimental strategies for overcoming doping bottlenecks as discussed by the authors.

TL;DR: This work predicts a continuous transition from the normal insulator to a topological insulator and eventually to a metal as a function of F⊥ on few-layer phosphorene, and opens the possibility of converting normal insulators into topological ones via electric field and making a multifunctional "field effect topological transistor" that could manipulate simultaneously both spin and charge carrier.

TL;DR: In this paper, the spectroscopic behavior of colloidal InP quantum dots (QDs) has been investigated as a function of the mean QD diameter (which ranged from 26 to 60 A).

TL;DR: In this paper, a computational method that maps the energy eigenvalues obtained from large supercell calculations into an effective band structure (EBS) and recovers an approximate $E(stackrel{P\vec{k})$ for alloys is described.
