Thesis (Ph.D.)--Stanford University, 2005.

Carbon nanotubes are chemically derived quantum wires (diameter &sim;1 nm) with atomically well-defined structures, and are ideal for elucidating basic phenomena in 1-D and have been proposed as the potential building blocks for future nanoelectronics. In this thesis, I will discuss the electrical properties of carbon nanotubes under axial stretching and their performance as a nano-electromechanical-system which is found superior to typical silicon micro-electro-mechanical-system (MEMS). I will also describe novel suspended nanotube device structures integrated with a local metal gate, which makes them superior quantum systems compared to nanotubes pinned on substrate. Such devices have enabled us to probe the band structures of nanotubes including nonlinear band dispersion and have led to observations of interesting physical phenomena such as Fabry-Perot interference, single electron transistor behavior, Aharonov-Bohm effects, quantum state shell-filling, -splitting and -crossing in magnetic field arising from well-defined molecular orbitals reflective of the nanotube chirality. The high quality transport data also reveal correlation between the contact junction resistance and the various transport regimes in single walled carbon nanotube devices.
