Journal ArticleDOI
Fast Sensing of Double-Dot Charge Arrangement and Spin State with a Radio-Frequency Sensor Quantum Dot
Christian Barthel,Morten Kjaergaard,Morten Kjaergaard,James Medford,Michael Stopa,Charles Marcus,Micah Hanson,Arthur C. Gossard +7 more
TL;DR: In this paper, a single-shot measurement of the charge arrangement and spin state of a double quantum dot is reported with measurement times down to 100 ns, using radiofrequency reflectometry of a proximal quantum dot in the Coulomb blockade regime.
Journal ArticleDOI
Quantum dot self-consistent electronic structure and the Coulomb blockade.
TL;DR: The existence of a shell structure in the dot levels is demonstrated which results in envelope modulation of Coulomb oscillation peak heights, influences the dot capacitances and possibly contributes to departure of recent experimental results from the predictions of random-matrix theory.
Journal ArticleDOI
Single-electron delocalization in hybrid vertical-lateral double quantum dots.
TL;DR: By using nonlinear transport measurements of “Coulomb diamonds,” it is shown that an inherent asymmetry in the capacitances of the component dots influences the diamond slopes, thereby allowing for the determination of the dot through which the electron has passed.
Journal ArticleDOI
Triple quantum dot charging rectifier
TL;DR: In this paper, the Coulomb blockade regime was applied to three tunnel-coupled quantum dots in a GaAs∕Al0.3Ga0.7As heterostructure containing a two-dimensional electron gas using lithographically patterned gates.
Journal ArticleDOI
On the chemical bonding effects in the Raman response: Benzenethiol adsorbed on silver clusters
TL;DR: In this paper, the effects of chemical bonding on Raman scattering from benzenethiol chemisorbed on silver clusters using time-dependent density functional theory (TDDFT) are computed using a formalism that employs analytical derivatives of frequency-dependent electronic polarizabilities.
