Biexciton fine structure in monolayer transition metal dichalcogenides
Alexander Steinhoff, Matthias Florian, Akshay Singh +8
The optical properties of atomically thin transition metal dichalcogenide (TMDC) semiconductors are shaped by the emergence of correlated many-body complexes due to strong Coulomb…
Excitons versus electron-hole plasma in monolayer transition metal dichalcogenide semiconductors
Alexander Steinhoff, Matthias Florian, Malte Rösner +3
When electron-hole pairs are excited in a semiconductor, it is a priori not clear if they form a fermionic plasma of unbound particles or a bosonic exciton gas. Usually, the excito…
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…
Quantum-Confined Stark Effect in polar and nonpolar Wurtzite InN/GaN Heterostructures: Influence on Electronic Structure and Compensation by Coulomb Attraction
Stefan Barthel, Kolja Schuh, Oliver Marquardt +4
In this paper we systematically analyze the electronic structures of polar and nonpolar wurtzite-InN/GaN quantum dots and their modification due to the quantum-confined Stark effec…
Influence of symmetry and Coulomb-correlation effects on the optical properties of nitride quantum dots
N. Baer, S. Schulz, P. Gartner +3
The electronic and optical properties of self-assembled InN/GaN quantum dots (QDs) are investigated by means of a tight-binding model combined with configuration interaction calcul…
