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…
Seeing moiré superlattices
L. J. McGilly, A. Kerelsky, N. R. Finney +17
Moiré superlattices in van der Waals (vdW) heterostructures have given rise to a number of emergent electronic phenomena due to the interplay between atomic structure and electron…
Novel mechanisms to enhance the capacitance beyond the classical limits in capacitors with free-electron-like electrodes
Javier Junquera, Pablo García-Fernández, Massimiliano Stengel
The so-called negative electron compressibility refers to the lowering of the chemical potential of a metallic system when the carrier density increases. This effect has often been…
