Efficient and Continuous Microwave Photodetection in Hybrid Cavity-Semiconductor Nanowire Double Quantum Dot Diodes
Waqar Khan, Patrick P. Potts, Sebastian Lehmann +4
Single photon detectors are key for time-correlated photon counting applications [1] and enable a host of emerging optical quantum information technologies [2]. So far, the leading…
Selective tuning of spin-orbital Kondo contributions in parallel-coupled quantum dots
Heidi Potts, Martin Leijnse, Adam Burke +4
We use co-tunneling spectroscopy to investigate spin-, orbital-, and spin-orbital Kondo transport in a strongly confined system of InAs double quantum dots (QDs) parallel-coupled t…
Radial etching of strongly confined crystal-phase defined quantum dots
Markus Aspegren, Chris Mkolongo, Sebastian Lehmann +3
We realize strongly confined quantum dots (QDs) in InAs nanowires (NWs) by combining epitaxial crystal-phase control with chemical wet etching. A strong axial confinement is first…
Gate control, g-factors and spin orbit energy of p-type GaSb nanowire quantum dot devices
Sven Dorsch, In-Pyo Yeo, Sebastian Lehmann +3
Proposals for quantum information applications are frequently based on the coherent manipulation of spins confined to quantum dots. For these applications, p-type III-V material sy…
Unconventional cross sections in zinc phosphide nanowires grown using exclusively earth-abundant components
Simon Escobar Steinvall, Hampus Thulin, Nico Kawashima +8
To enable lightweight and flexible solar cell applications it is imperative to develop direct bandgap absorber materials. Moreover, to enhance the potential sustainability impact o…
Orthogonal Graph Drawing with Inflexible Edges
Thomas Bläsius, Sebastian Lehmann, Ignaz Rutter
We consider the problem of creating plane orthogonal drawings of 4-planar graphs (planar graphs with maximum degree 4) with constraints on the number of bends per edge. More precis…
