Coulomb blockade in suspended Si3N4 -coated single-walled carbon nanotubes
(AIP Publishing, 2004)Uniform coaxial coating of suspended single-walled carbon nanotubes with high-quality dielectric silicon nitride has been obtained by low-pressure chemical vapor deposition. A three-terminal device has been demonstrated ... -
Electrical and thermoelectric transport in mixed-dimensional graphitic mesoscopic systems
(2022-09-12)Confining electrons to fewer than three spatial dimensions increases the relative strength of potential to kinetic energy, which can generate a wide variety of novel emergent quantum phenomena. I will discuss three experiments ... -
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 ... -
Embedding a Carbon Nanotube across the Diameter of a Solid State Nanopore
(American Vacuum Society, 2011)A fabrication method for positioning and embedding a single-walled carbon nanotube (SWNT) across the diameter of a solid state nanopore is presented. Chemical vapor deposition (CVD) is used to grow SWNTs over arrays of ... -
Growth and fabrication with single-walled carbon nanotube probe microscopy tips
(American Institute of Physics, 2000)Single-walled carbon nanotube (SWNT) probe microscopy tips were grown by a surface growth chemical vapor deposition method. Tips consisting of individual SWNTs (1.5–4 nm in diameter) and SWNT bundles (4–12 nm in diameter) ... -
Nanoscience and the nano-bioelectronics frontier
(Springer Science + Business Media, 2015)This review describes work presented in the 2014 inaugural Tsinghua University Press-Springer Nano Research Award lecture, as well as current and future opportunities for nanoscience research at the interface with brain ... -
Patterned growth of single-walled carbon nanotube arrays from a vapor-deposited Fe catalyst
(AIP Publishing, 2003)Single-walled carbon nanotubes have been grown on a variety of substrates by chemical vapor deposition using low-coverage vacuum-deposited iron as a catalyst. Ordered arrays of suspended nanotubes ranging from submicron ... -
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 ... -
Room-temperature single charge sensitivity in carbon nanotube field-effect transistors
(AIP Publishing, 2006)Electrical current fluctuation studies are reported for coaxial pp-type and nn-type single-wall carbon nanotubefield-effect transistors(FETs). Abrupt discrete switching of the source-drain current is observed at room ...
