Application of Host−Guest Chemistry in Nanotube-Based Device Fabrication: Photochemically Controlled Immobilization of Azobenzene Nanotubes on Patterned α-CD Monolayer/Au Substrates via Molecular Recognition
Journal of the American Chemical Society, 2003Co-Authors: Ipsita A. Banerjee, Hiroshi MatsuiAbstract:Azobenzene-functionalized Nanotubes recognized and attached onto well-defined complementary regions of thiolated α-CD SAM/Au substrates via host−guest molecular recognition. The binding between the azobenzene Nanotubes and the α-CD SAM/Au substrates was controlled by UV irradiation. The light-induced attachment−detachment of the azobenzene Nanotubes on the α-CD SAMs was reversible. Some of the Nanotubes were capable of interconnecting two Au substrates. This smart building block may be applied to build photoactive nanometer-sized mechanical switches in electronics.

surface science mems and nems progress and opportunities for surface science research performed on or by microDevices
Progress in Surface Science, 2013Co-Authors: Diana Berman, J KrimAbstract:Abstract Micro- and Nano-Electro-Mechanical Systems (MEMS and NEMS) represent existing (MEMS) and emerging (NEMS) technologies Based on microfabrication of micron to nanometer scale miniature mechanical components (gears, latches, mirrors, etc.) that are integrated with electrical elements to allow for electro-mechanical actuation and/or capacitive displacement detection. One common aspect of MEMS and NEMS Devices is that they have mechanical functionality that may include moveable parts whose motion is controlled by external electrical connections. Current fabrication methods, along with high surface to volume ratios, make MEMS and NEMS Devices highly susceptible to surface forces and adsorbed surface species, to the point where the Devices are now being increasingly utilized as sensitive probes in fundamental surface science studies. This sensitivity can potentially be used to great advantage if the Devices can be made to operate reproducibly in well controlled environments. This review highlights a number of such recent studies, beginning with an overview of the fabrication processes employed for silicon, metal, diamond, graphene and carbon Nanotube – Based Device technologies. A discussion of how traditional surface science studies on passive two-dimensional substrates compare to and contrast with studies performed on, or by, MEMS and/or NEMS Devices, is also included. The overall goal is to highlight areas of current opportunity for surface scientists in the flourishing arena of micro- and nano-Device fabrication and technology.

Charge transfer between semiconducting carbon Nanotubes and their doped GaAs(110) and InAs(110) substrates detected by scanning tunnelling spectroscopy
Nanotechnology, 2007Co-Authors: Laura B. Ruppalt, Joseph W. LydingAbstract:Ultrahigh vacuum (UHV) scanning tunnelling microscopy (STM) and spectroscopy (STS) have been used to examine the role of substrate doping and composition in determining the electronic behaviour of semiconducting single-walled carbon Nanotubes (SWNT) deposited onto III–V(110) surfaces. Hybrid SWNT/III–V(110) systems were created through sample cleavage and subsequent Nanotube transfer in UHV. Room temperature STS spectra indicate electron transfer from the n-GaAs substrate to the supported SWNT and from the SWNT to the p-GaAs substrate, resulting in the respective n-type and p-type doping of the Nanotube upon adsorption. STS measurements on InAs(110) supported carbon Nanotubes are less uniform, with selected SWNTs on the n-InAs(110) surface exhibiting distinct electronic changes when shifted into registration with the substrate lattice. No such orientation sensitivity is detected in Nanotubes on GaAs surfaces. The potential for systematic modification of a SWNT's electronic behaviour through intentional substrate engineering could present a new avenue for the design and fabrication of Nanotube-Based Device structures.
