Strain distribution in zincblende and wurtzite GaAs nanowires bent by a one-sided (In, Al)As stressor shell: consequences for torsion, chirality, and piezoelectricity
Yiannis Hadjimichael, Oliver Brandt, Christian Merdon +2
We present a finite-strain model that is capable of describing the large deformations in bent nanowire heterostructures. The model incorporates a nonlinear strain formulation deriv…
Tailoring Photoluminescence by Strain-Engineering in Layered Perovskite Flakes
Davide Spirito, María Barra-Burillo, Francesco Calavalle +6
Strain is an effective strategy to modulate the optoelectronic properties of 2D materials, but it has been almost unexplored in layered hybrid organic-inorganic metal halide perovs…
Thermal expansion and temperature dependence of Raman modes in epitaxial layers of Ge and GeSn
Agnieszka Anna Corley-Wiciak, Diana Ryzhak, Marvin Hartwig Zoellner +7
Temperature dependence of vibrational modes in semiconductors depends on lattice thermal expansion and anharmonic phonon-phonon scattering. Evaluating the two contributions from ex…
Tunability and Losses of Mid-infrared Plasmonics in Heavily Doped Germanium Thin Films
Jacopo Frigerio, Andrea Ballabio, Giovanni Isella +16
Heavily-doped semiconductor films are very promising for application in mid-infrared plasmonic devices because the real part of their dielectric function is negative and broadly tu…
Modeling of strain-induced Pockels effect in Silicon
Costanza Lucia Manganelli, Paolo Pintus, Claudio Bonati
We propose a theoretical model to describe the strain-induced linear electro-optic (Pockels) effect in centro-symmetric crystals. The general formulation is presented and the speci…
