Luminescent emission of excited Rydberg excitons from monolayer WSe2
Shao-Yu Chen, Zhengguang Lu, Thomas Goldstein +11
We report the experimental observation of radiative recombination from Rydberg excitons in a two-dimensional semiconductor, monolayer WSe2, encapsulated in hexagonal boron nitride.…
Momentum-space indirect interlayer excitons in transition metal dichalcogenide van der Waals heterostructures
Jens Kunstmann, Fabian Mooshammer, Philipp Nagler +9
Monolayers of transition metal dichalcogenides (TMDCs) feature exceptional optical properties that are dominated by excitons, tightly bound electron-hole pairs. Forming van der Waa…
Localized defect states in MoS monolayers: electronic and optical properties
Jens Kunstmann, Tsegabirhan B. Wendumu, Gotthard Seifert
Defects usually play an important role in tuning and modifying various properties of semiconducting or insulating materials. Therefore we study the impact of point and line defects…
Unveiling the atomic structure of single-wall boron nanotubes
Jens Kunstmann, Viktor Bezugly, Hauke Rabbel +2
Despite recent successes in the synthesis of boron nanotubes (BNTs), the atomic arrangement of their walls has not yet been determined and many questions about their basic properti…
Multiscale Modeling of Nanowire-based Schottky-Barrier Field-Effect Transistors for Sensor Applications
Daijiro Nozaki, Jens Kunstmann, Felix Zörgiebel +3
We present a theoretical framework for the calculation of charge transport through nanowire-based Schottky-barrier field-effect transistors that is conceptually simple but still ca…
