Heat Conduction and Energy Relaxation in an InAs Nanowire Approaching the Clean One-Dimensional Limit
Subhomoy Haldar, Diego Subero, Mukesh Kumar +5
We investigate heat conduction and energy relaxation in an InAs semiconductor nanowire using a hybrid semiconductor-superconductor architecture. Local electronic temperatures are m…
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…
Combined Light Excitation and Scanning Gate Microscopy on Heterostructure Nanowire Photovoltaic Devices
Yen-Po Liu, Jonatan Fast, Yang Chen +5
Nanoscale optoelectronic components achieve functionality via spatial variation in electronic structure induced by composition, defects, and dopants. To dynamically change the loca…
Geometric symmetry breaking and nonlinearity can increase thermoelectric power
Jonatan Fast, Hanna Lundström, Sven Dorsch +4
Direct thermal-to-electric energy converters typically operate in the linear regime, where the ratio of actual maximum power relative to the ideal maximum power, the so-called fill…
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…
Hot-Carrier Separation in Heterostructure Nanowires observed by Electron-Beam Induced Current
Jonatan Fast, Enrique Barrigon, Mukesh Kumar +7
The separation of hot carriers in semiconductors is of interest for applications such as thermovoltaic photodetection and third-generation photovoltaics. Semiconductor nanowires of…
