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.…
