• #### Carbon Nanotubes for Coherent Spintronics ﻿

(Elsevier Science Limited, 2010)
Carbon nanotubes bridge the molecular and crystalline quantum worlds, and their extraordinary electronic, mechanical and optical properties have attracted enormous attention from a broad scientific community. We review ...
• #### Electron–Nuclear Interaction in $^{13}C$ Nanotube Double Quantum Dots ﻿

(Nature Publishing Group, 2009)
For coherent electron spins, hyperfine coupling to nuclei in the host material can either be a dominant source of unwanted spin decoherence or, if controlled effectively, a resource enabling storage and retrieval of quantum ...
• #### Quantum Dots in Gated Nanowires and Nanotubes ﻿

(2012-08-17)
This thesis describes experiments on quantum dots made by locally gating one-dimensional quantum wires. The first experiment studies a double quantum dot device formed in a Ge/Si core/shell nanowire. In addition to measuring ...
• #### Relaxation and Dephasing in a Two-Electron $^{13}C$ Nanotube Double Quantum Dot ﻿

(American Physical Society, 2009)
We use charge sensing of Pauli blockade (including spin and isospin) in a two-electron $^{13}C$ nanotube double quantum dot to measure relaxation and dephasing times. The relaxation time $T_1$ first decreases with a ...
• #### Spin-orbit effects in carbon-nanotube double quantum dots ﻿

(American Physical Society (APS), 2010)
We study the energy spectrum of symmetric double quantum dots in narrow-gap carbon nanotubes with one and two electrostatically confined electrons in the presence of spin-orbit and Coulomb interactions. Compared to GaAs ...
