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…
Directional Roll-up of Nanomembranes Mediated by Wrinkling
P. Cendula, S. Kiravittaya, I. Mönch +2
We investigate the relaxation of rectangular wrinkled thin films intrinsically containing an initial strain gradient. A preferential rolling direction, depending on wrinkle geometr…
Heterogeneous confinement in laterally coupled InGaAs/GaAs quantum dot molecules under lateral electric fields
Jie Peng, Claus Hermannstädter, Marcus Witzany +7
We study the electronic and optical properties of laterally coupled InGaAs/GaAs quantum dot molecules under lateral electric field. We find that electrons perceive the double-dot s…
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…
Bidirectional wavelength tuning of semiconductor quantum dots as artificial atoms in an optical resonator
S. Mendach, S. Kiravittaya, A. Rastelli +3
We consider a pair of artificial atoms with different ground state energies. By means of finite element calculations we predict that the ground state energies can be tuned into res…
Semiconductor sub-micro-/nanochannel networks by deterministic layer wrinkling
Yongfeng Mei, Dominic J. Thurmer, Francesca Cavallo +2
we demonstrate a technology "Release and bond-back of layers (REBOLA)" that exploits the deterministic wrinkling of a semiconductor layer to create well-defined and versatile nanoc…
