Non-invasive control of excitons in two-dimensional materials
Christina Steinke, Daniel Mourad, Malte Rösner +5
We investigate how external screening shapes excitons in two-dimensional (2d) semiconductors embedded in laterally structured dielectric environments. An atomic scale view of these…
Determination of the Fermi Level Position in Dilute Magnetic GaMnN Films
Stefan Barthel, Gerd Kunert, Mariuca Gartner +6
We report on a combined theoretical and experimental determination of the Fermi level position in wurtzite GaMnN films with and as grown by molecular…
Theory of band gap bowing of disordered substitutional II-VI and III-V semiconductor alloys
Daniel Mourad, Gerd Czycholl
For a wide class of technologically relevant compound III-V and II-VI semiconductor materials AC and BC mixed crystals (alloys) of the type A(x)B(1-x)C can be realized. As the elec…
Multiband tight-binding theory of disordered ABC semiconductor quantum dots: Application to the optical properties of alloyed CdZnSe nanocrystals
Daniel Mourad, Gerd Czycholl
Zero-dimensional nanocrystals, as obtained by chemical synthesis, offer a broad range of applications, as their spectrum and thus their excitation gap can be tailored by variation…
Band gap bowing of binary alloys: Experimental results compared to theoretical tight-binding supercell calculations for CdZnSe
Daniel Mourad, Carsten Kruse, Sebastian Klembt +5
Compound semiconductor alloys of the type ABC find widespread applications as their electronic bulk band gap varies continuously with x, and therefore a tayloring of the energy gap…
Multiband effective bond-orbital model for nitride semiconductors with wurtzite structure
Daniel Mourad, Stefan Barthel, Gerd Czycholl
A multiband empirical tight-binding model for group-III-nitride semiconductors with a wurtzite structure has been developed and applied to both bulk systems and embedded quantum do…
