Gate-Defined Graphene Quantum Point Contact in the Quantum Hall Regime
S. Nakaharai, J. R. Williams, C. M. Marcus
We investigate transport in a gate-defined graphene quantum point contact in the quantum Hall regime. Edge states confined to the interface of p and n regions in the graphene sheet…
Composition profiling InAs quantum dots and wetting layers by atom probe tomography and cross-sectional scanning tunnelling microscopy
A. D. Giddings, J. G. Keizer, M. Hara +4
This study compares cross-sectional scanning tunnelling microscopy (XSTM) and atom probe tomography (APT). We use epitaxially grown self-assembled InAs quantum dots (QDs) in GaAs a…
Interference of dissimilar photon sources
A. J. Bennett, R. B. Patel, C. A. Nicoll +2
If identical photons meet at a semi-transparent mirror they appear to leave in the same direction, an effect called "two-photon interference". It has been known for some time that…
Robustness of Charge-Qubit Cluster States to Double Quantum Point Contact Measurement
Tetsufumi Tanamoto
We theoretically investigate the robustness of cluster states in charge qubit system based on quantum dot (QD) and double quantum point contact (DQPC). Trap state is modeled by an…
Numerical approach for retention characteristics of double floating-gate memories
Tetsufumi Tanamoto, Kouichi Muraoka
We report on a numerical investigation in which memory characteristics of double floating-gate (DFG) structure were compared to those of the conventional single floating-gate struc…
Photoluminescence from silicon dioxide photonic crystal cavities with embedded silicon nanocrystals
Yiyang Gong, Satoshi Ishikawa, Szu-Lin Cheng +2
One dimensional nanobeam photonic crystal cavities are fabricated in silicon dioxide with silicon nanocrystals. Quality factors of over 9 x 10^3 are found in experiment, matching t…
