Exact long-range dielectric screening and interatomic force constants in quasi-2D crystals
Miquel Royo, Massimiliano Stengel
We develop a fundamental theory of the long-range electrostatic interactions in two-dimensional crystals by performing a rigorous study of the nonanalyticities of the Coulomb kerne…
Direct and converse flexoelectricity in two-dimensional materials
Matteo Springolo, Miquel Royo, Massimiliano Stengel
Building on recent developments in electronic-structure methods, we define and calculate the flexoelectric response of two-dimensional (2D) materials fully from first principles. I…
Electron and phonon transport in twisted graphene nanoribbons
Aleandro Antidormi, Miquel Royo, Riccardo Rurali
We theoretically study the electrical, thermal and thermoelectric transport properties of graphene nanoribbons under torsional deformations. The modelling follows a nonequilibrium…
Tailoring the core electron density in modulation-doped Core-Multi-Shell nanowires
Fabrizio Buscemi, Miquel Royo, Guido Goldoni +1
We show how a proper radial modulation of the composition of core-multi-shell nanowires critically enhances the control of the free-carrier density in the high-mobility core with r…
Prediction of inelastic light scattering spectra from electronic collective excitations in GaAs/AlGaAs core-multishell nanowires
Miquel Royo, Andrea Bertoni, Guido Goldoni
We predict inelastic light scattering spectra from electron collective excitations in a coaxial quantum well embedded in a core-multishell GaAs/AlGaAs nanowire. The complex composi…
Coulomb interaction signatures in self-assembled lateral quantum dot molecules
Xinran. Zhou, Jihoon. Lee, Gregory. J. Salamo +3
We use photoluminescence spectroscopy to investigate the ground state of single self-assembled InGaAs lateral quantum dot molecules. We apply a voltage along the growth direction t…
