Quantised Charge Transport driven by a Surface Acoustic Wave in induced unipolar and bipolar junctions
Yousun Chung, Hangtian Hou, Seok-Kyun Son +7
Surface acoustic waves (SAWs) have been used to transport single electrons across long distances of several hundreds of microns. They can potentially be instrumental in the impleme…
Quantised conductance of one-dimensional strongly-correlated electrons in an oxide heterostructure
H. Hou, Y. Kozuka, Jun-Wei Liao +7
Oxide heterostructures are versatile platforms with which to research and create novel functional nanostructures. We successfully develop one-dimensional (1D) quantum-wire devices…
Sound-driven single-electron transfer in a circuit of coupled quantum rails
Shintaro Takada, Hermann Edlbauer, Hugo V. Lepage +13
Surface acoustic waves (SAWs) strongly modulate the shallow electric potential in piezoelectric materials. In semiconductor heterostructures such as GaAs/AlGaAs, SAWs can thus be e…
Long-lived non-equilibrium superconductivity in a non-centrosymmetric Rashba semiconductor
V. Narayan, P. C. Verpoort, J. R. A. Dann +8
We report non-equilibrium magnetodynamics in the Rashba-superconductor GeTe, which lacks inversion symmetry in the bulk. We find that at low temperature the system exhibits a non-e…
Au-Ge alloys for wide-range low-temperature on-chip thermometry
J. R. A. Dann, P. C. Verpoort, J. Ferreira de Oliveira +4
We present results of a Au-Ge alloy that is useful as a resistance-based thermometer from room temperature down to at least \SI{0.2}{\kelvin}. Over a wide range, the electrical res…
Single-photon Emission from an Acoustically-driven Lateral Light-emitting Diode
Tzu-Kan Hsiao, Antonio Rubino, Yousun Chung +12
Single-photon sources are essential building blocks in quantum photonic networks, where quantum-mechanical properties of photons are utilised to achieve quantum technologies such a…
