Adamantanes as white-light emitters: Controlling arrangement and functionality by external Coulomb forces
Jürgen Belz, Johannes Haust, Marius J. Müller +10
Functionalized adamantane molecular cluster materials show highly transient nonlinear optical properties of currently unclear structural origin. Several interaction mechanisms in c…
White-light generating molecular materials: correlation between the amorphous/crystalline structure and nonlinear optical properties
Johannes Haust, Jürgen Belz, Marius Müller +11
Amorphous materials are integral part of todays technology, they commonly are performant and versatile in integration. Consequently, future applications increasingly aim to harvest…
Ab-initio calculation of band alignments for opto-electronic simulations
Jan Oliver Oelerich, Maria J. Weseloh, Kerstin Volz +1
A modified core-to-valence band maximum approach is applied to calculate band offsets of strained III/V semiconductor hetero junctions. The method is used for the analysis of (In,G…
Coherent optical and acoustic phonons generated at lattice-matched GaP/Si(001) heterointerfaces
Kunie Ishioka, Andreas Beyer, Wolfgang Stolz +4
Thin GaP films can be grown on an exact Si(001) substrate with nearly perfect lattice match. We perform all-optical pump-probe measurements to investigate the ultrafast electron-ph…
Valence band-anticrossing in GaPBi dilute bismide alloys: giant bowing of the band gap and spin-orbit splitting energy
Zoe L. Bushell, Christopher A. Broderick, Lukas Nattermann +5
Using spectroscopic ellipsometry measurements on GaPBi/GaP epitaxial layers up to % we observe a giant bowing of the direct band gap () and valence…
