The macroscopic electric polarization of a crystal is often defined as the dipole of a unit cell.
In fact, such a dipole moment is ill defined, and the above definition is incorrect. Looking …

Theories of electron scattering by ionized impurities in semiconductors are reviewed. The
early foundations based on the Born approximation and their subsequent refinements are …

The reliable production of two-dimensional (2D) crystals is essential for the development of
new technologies based on 2D materials. However, current synthesis methods suffer from a …

We probe the accuracy limit of ab initio calculations of carrier mobilities in semiconductors,
within the framework of the Boltzmann transport equation. By focusing on the paradigmatic …

Charged excitons, or X±trions, in monolayer transition-metal dichalcogenides have binding
energies of several tens of meV. Together with the neutral exciton X 0 they dominate the …

Abstract 2D elemental layered crystals, such as graphene and black phosphorus (B‐P),
have received tremendous attentions due to their rich physical and chemical properties. In …

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 Å). Absorption spectra show …

In this Letter, we map for the first time the current distribution among the individual layers of
multilayer two-dimensional systems. Our findings suggest that in a multilayer MoS2 field …

Solid-state defects acting as single photon sources and quantum bits are leading
contenders in quantum technologies. Despite great efforts, not all the properties and …

We present a pseudopotential approach to the calculation of the excitonic spectrum of
semiconductor quantum dots. Starting from a many-body expansion of the exciton wave …
