Charge State Hysteresis in Semiconductor Quantum Dots
C. H. Yang, A. Rossi, N. S. Lai +3
Semiconductor quantum dots provide a two-dimensional analogy for real atoms and show promise for the implementation of scalable quantum computers. Here, we investigate the charge c…
Printed Circuit Board Metal Powder Filters for Low Electron Temperatures
Filipp Mueller, Raymond N. Schouten, Matthias Brauns +6
We report the characterisation of printed circuit boards (PCB) metal powder filters and their influence on the effective electron temperature which is as low as 22 mK for a quantum…
Spin-valley lifetimes in a silicon quantum dot with tunable valley splitting
C. H. Yang, A. Rossi, R. Ruskov +7
Although silicon is a promising material for quantum computation, the degeneracy of the conduction band minima (valleys) must be lifted with a splitting sufficient to ensure format…
Orbital and valley state spectra of a few-electron silicon quantum dot
C. H. Yang, W. H. Lim, N. S. Lai +3
Understanding interactions between orbital and valley quantum states in silicon nanodevices is crucial in assessing the prospects of spin-based qubits. We study the energy spectra…
Overlapping-gate architecture for silicon Hall bar MOSFET devices in the low electron density and high magnetic field regime
Laurens H. Willems Van Beveren, Kuan Y. Tan, Nai-Shyan Lai +3
A common issue in low temperature measurements of enhancement-mode metal-oxide-semiconductor (MOS) field-effect transistors (FETs) in the low electron density regime is the high co…
Single-electron shuttle based on a silicon quantum dot
K. W. Chan, M. Mottonen, A. Kemppinen +4
We report on single-electron shuttling experiments with a silicon metal-oxide-semiconductor quantum dot at 300 mK. Our system consists of an accumulated electron layer at the Si/Si…
