Electron g-factor determined for quantum dot circuit fabricated from (110)-oriented GaAs quantum well
T. Nakagawa, S. Lamoureux, T. Fujita +8
The choice of substrate orientation for semiconductor quantum dot circuits offers opportunities for tailoring spintronic properties such as g-factors for specific functionality. In…
Effects of biased and unbiased illuminations on dopant-free GaAs/AlGaAs 2DEGs
A. Shetty, F. Sfigakis, W. Y. Mak +16
Illumination is performed at low temperature on dopant-free two-dimensional electron gases (2DEGs) of varying depths, under unbiased (gates grounded) and biased (gates at a positiv…
Phase Diagram of Quantum Hall Breakdown and Non-linear Phenomena for InGaAs/InP Quantum Wells
V. Yu, M. Hilke, P. J. Poole +2
We investigate non-linear magneto-transport in a Hall bar device made from a strained InGaAs/InP quantum well: a material system with attractive spintronic properties. From extensi…
Tuning the electrically evaluated electron Lande g factor in GaAs quantum dots and quantum wells of different well widths
G. Allison, T. Fujita, K. Morimoto +9
We evaluate the Lande g factor of electrons in quantum dots (QDs) fabricated from GaAs quantum well (QW) structures of different well width. We first determine the Lande electron g…
Single Photoelectron Detection after Selective Excitation of Electron-Heavy Hole and Electron-Light Hole Pairs in Double Quantum Dots
K. Morimoto, T. Fujita, G. Allison +9
We demonstrate the real-time detection of single photogenerated electrons in two different lateral double quantum dots made in AlGaAs/GaAs/AlGaAs quantum wells having a thin or a t…
Experimental Phonon Band Structure of Graphene using C^{13}$ Isotopes
Simon Bernard, Eric Whiteway, Victor Yu +2
Using very uniform large scale chemical vapor deposition grown graphene transferred onto silicon, we were able to identify 15 distinct Raman lines associated with graphene monolaye…
