Electronic structure of GaSb/AlGaSb quantum dots formed by filling droplet-etched nanoholes
Lucie Leguay, Abhiroop Chellu, Joonas Hilska +4
Epitaxially-grown semiconductor quantum dots (QDs) provide an attractive platform for the development of deterministic sources of high-quality quantum states of light. Such non-cla…
The Emission Directionality of Electronic Intraband Transitions in Stacked Quantum Dots
Alexander Mittelstädt, Ludwig A. Th. Greif, Andrei Schliwa
We investigate the emission directionality of electronic intraband (intersubband) transitions in stacked coupled quantum dots. Using a well-established eight-band metho…
Efficient electronic structure calculations for extended systems of coupled quantum dots using a linear combination of quantum dot orbitals method
Alexander Mittelstädt, Ludwig A. Th. Greif, Stefan T. Jagsch +1
We present a novel "linear combination of atomic orbitals"-type of approximation, enabling accurate electronic structure calculations for systems of up to 20 or more electronically…
Terahertz Lasing at Roomtemperature: Numerical Study of a Vertical-Emitting Quantum Cascade Laser Based on a Quantum Dot Superlattice
Alexander Mittelstädt, Ludwig A. Th. Greif, Stefan T. Jagsch +1
We investigate room temperature lasing of terahertz quantum cascade lasers using quantum dot chains as active material suitable for wireless communication and imaging technologies.…
Electronic states of (InGa)(AsSb)/GaAs/GaP quantum dots
Petr Klenovský, Andrei Schliwa, Dieter Bimberg
Detailed theoretical studies of the electronic structure of (InGa)(AsSb)/GaAs/GaP quantum dots are presented. This system is unique since it exhibits concurrently direct and indire…
Ground State Resonant Two-Photon Transitions in Wurtzite GaN/AlN Quantum Dots
Stefan Thomas Jagsch, Ludwig Albrecht Thorsten Greif, Stephan Reitzenstein +1
Two-photon transition rates are investigated in resonance to the ground state in wurtzite GaN/AlN quantum dots. The ground state transition is two-photon allowed because of the ele…
