Direct experimental determination of the spontaneous polarization of GaN
Jonas Lähnemann, Oliver Brandt, Uwe Jahn +8
We present a universal approach for determining the spontaneous polarization Psp of a wurtzite semiconductor from the emission energies of excitons bound to the different types of…
Impurity-induced step interactions: a kinetic Monte-Carlo study
Jürgen Vollmer, József Hegedüs, Frank Grosse +1
A one-dimensional continuum description of growth on vicinal surfaces in the presence of immobile impurities predicts that the impurities can induce step bunching when they suppres…
Electron-Phonon Interaction in Embedded Semiconductor Nanostructures
Frank Grosse, Roland Zimmermann
The modification of acoustic phonons in semiconductor nanostructures embedded in a host crystal is investigated including corrections due to strain within continuum elasticity theo…
Optical exciton Aharonov-Bohm effect, persistent current, and magnetization in semiconductor nanorings of type I and II
M. Grochol, F. Grosse, R. Zimmermann
The optical exciton Aharonov-Bohm effect, i. e. an oscillatory component in the energy of optically active (bright) states, is investigated in nanorings. It is shown that a small e…
