This article describes recent technical developments that have made the total-energy pseudopotential the most powerful ab initio quantum-mechanical modeling method presently ava...
Measurements of the Hall voltage of a two-dimensional electron gas, realized with a silicon metal-oxide-semiconductor field-effect transistor, show that the Hall resistance at p...
Abstract The transition metal dichalcogenides are about 60 in number. Two-thirds of these assume layer structures. Crystals of such materials can be cleaved down to less than 10...
The study of the photophysical properties of organic-metallic lead halide perovskites, which demonstrate excellent photovoltaic performance in devices with electron- and hole-ac...
Abstract A summary is given of what is now known about the existence of localized states for electrons in three-dimensional disordered systems, and what can be conjectured about...
The lattice spacing of aluminium has been measured as a function of temperature by means of a high-temperature Debye-Scherrer X-ray camera. The coefficient of expansion has been...
