Low-density InGaAs/AlGaAs Quantum Dots in Droplet-Etched Nanoholes
Saimon F. Covre Da Silva, Ailton J. Garcia, Maximilian Aigner +10
Over the past two decades, epitaxial semiconductor quantum dots (QDs) have demonstrated very promising properties as sources of single photons and entangled photons on-demand. Amon…
Observation of Diode Behavior and Gate Voltage Control of Hybrid Plasmon-Phonon Polaritons in Graphene-Hexagonal Boron Nitride Heterostructures
Francisco C. B. Maia, Brian T. O'Callahan, Alisson R. Cadore +8
Light-matter interaction in two-dimension photonic materials allows for confinement and control of free-space radiation on sub-wavelength scales. Most notably, the van der Waals he…
Experimental realization of coexisting states of rolled-up and wrinkled nanomembranes by strain and etching control
Peter Cendula, Angelo Malachias, Christoph Deneke +2
Self-positioned nanomembranes such as rolled-up tubes and wrinkled thin films have been potential systems for a variety of applications and basic studies on elastic properties of n…
Bending and wrinkling as competing relaxation pathways for strained free-hanging films
P. Cendula, S. Kiravittaya, Y. Mei +2
An equilibrium phase diagram for the shape of compressively strained free-hanging films is developed by total strain energy minimization. For small strain gradients Δε, the film wr…
Structural and magnetic properties of an InGaAs/FeSi superlattice in cylindrical geometry
Ch. Deneke, J. Schumann, R. Engelhard +7
The structure and the magnetic properties of an InGaAs/Fe3Si superlattice in a cylindrical geometry are investigated by electron microscopy techniques, x-ray diffraction and magnet…
Direct strain and elastic energy evaluation in rolled-up semiconductor tubes by x-ray micro-diffraction
A. Malachias, Ch. Deneke, B. Krause +4
We depict the use of x-ray diffraction as a tool to directly probe the strain status in rolled-up semiconductor tubes. By employing continuum elasticity theory and a simple model w…
InGaAs/GaAs/alkanethiolate radial superlattices: Experimental
Christoph Deneke, Ute Zschieschang, Hagen Klauk +1
A radial InGaAs/GaAs/1-hexadecanethiol superlattice is fabricated by the roll-up of a strained InGaAs/GaAs bilayer passivated with a molecular self-assembled monolayer. Our techniq…
