Mesoscopic Elastic Distortions in GaAs Quantum Dot Heterostructures
Anastasios Pateras, Joonkyu Park, Youngjun Ahn +9
Quantum devices formed in high-electron-mobility semiconductor heterostructures provide a route through which quantum mechanical effects can be exploited on length scales accessibl…
Non-linear and dot-dependent Zeeman splitting in GaAs/AlGaAs quantum dot arrays
V. P. Michal, T. Fujita, T. A. Baart +5
We study the Zeeman splitting in lateral quantum dots that are defined in GaAs-AlGaAs het- erostructures by means of split gates. We demonstrate a non-linear dependence of the spli…
Coherent shuttle of electron-spin states
T. Fujita, T. A. Baart, C. Reichl +2
We demonstrate a coherent spin shuttle through a GaAs/AlGaAs quadruple-quantum-dot array. Starting with two electrons in a spin-singlet state in the first dot, we shuttle one elect…
Nanosecond-timescale spin transfer using individual electrons in a quadruple-quantum-dot device
T. A. Baart, N. Jovanovic, C. Reichl +2
The ability to coherently transport electron-spin states between different sites of gate-defined semiconductor quantum dots is an essential ingredient for a quantum-dot-based quant…
Coherent spin-exchange via a quantum mediator
T. A. Baart, T. Fujita, C. Reichl +2
Coherent interactions at a distance provide a powerful tool for quantum simulation and computation. The most common approach to realize an effective long-distance coupling 'on-chip…
Computer-automated tuning of semiconductor double quantum dots into the single-electron regime
T. A. Baart, P. T. Eendebak, C. Reichl +2
We report the computer-automated tuning of gate-defined semiconductor double quantum dots in GaAs heterostructures. We benchmark the algorithm by creating three double quantum dots…
Single-Spin CCD
Timothy Alexander Baart, Mohammad Shafiei, Takafumi Fujita +3
Spin-based electronics or spintronics relies on the ability to store, transport and manipulate electron spin polarization with great precision. In its ultimate limit, information i…
Gate defined zero- and one-dimensional confinement in bilayer graphene
Augustinus, M. Goossens, Stefanie C. M. Driessen +4
We report on the fabrication and measurement of nanoscale devices based on bilayer graphene sandwiched between hexagonal boron nitride bottom and top gate dielectrics. The top gate…
Transition Voltage Spectroscopy and the Nature of Vacuum Tunneling
M. L. Trouwborst, C. A. Martin, R. H. M. Smit +4
Transition Voltage Spectroscopy (TVS) has been proposed as a tool to analyze charge transport through molecular junctions. We extend TVS to Au-vacuum-Au junctions and study the dis…
