Giant flexoelectric effect in two-dimensional boron-nitride sheets
Ivan Naumov, Alexander M. Bratkovsky, V. Ranjan
We find, with the use of first-principles calculations, that a single-atom-thick boron-nitride (BN) sheet exhibits an unusual nonlinear electromechanical effect: it becomes macrosc…
Auger-mediated radiative recombination in three-dimensional silicon/silicon-germanium nanostructures
E. -K. Lee, D. J. Lockwood, J. -M. Baribeau +3
In a semiconductor heterostructure with type II energy band alignment, the spatial separation between electrons and holes slows down their radiative recombination. With increasing…
Unusual polarization patterns in flat epitaxial ferroelectric nanoparticles
Ivan I. Naumov, Alexander M. Bratkovsky
Interest in epitaxial ferroelectric nanoislands was growing rapidly in recent years driven by their potential for devices, especially ultradense memories. Recent advances in the "b…
Continuous theory of ferroelectric states in ultrathin films with real electrodes
A. M. Bratkovsky, A. P. Levanyuk
According to a continuous medium theory, in very thin ferroelectric films with real metallic electrodes (or dead layers near the electrodes) the domain structure reduces to sinusoi…
