12. Horizontal Growth and In Situ Assembly of Oriented Zinc Oxide Nanowires
Published: 10/1/2004
Authors: Babak Nikoobakht, Chris A Michaels, Stephan J Stranick, Mark D Vaudin
Abstract: The positioning and directed assembly of semiconductor nanowires (NWs) is of considerable current interest for bottom-up approaches to the engineering of intricate structures from nanoscale building blocks. We report a horizontal growth mode for ...

13. Template Fabrication of Protein-Functionalized Gold-Polypyrrole-Gold Segmented Nanowires
Published: 9/1/2004
Authors: R M Hernandez, Lee J Richter, Stephen Semancik, Stephan J Stranick, Thomas E. Mallouk
Abstract: Gold nanowires containing protein-modified poly(pyrrole) (Ppy) junctions were synthesized electrochemically using porous aluminum oxide as a template. The effects of the conditions of electrochemical synthesis on Ppy growth and protein (avidin or st ...

14. Controlling The Growth Direction of ZnO Nanowires (NWs) on c and a -Plane Sapphire
Published: 2/1/2004
Authors: Babak Nikoobakht, Albert Davydov, Stephan J Stranick
Abstract: The issue of controlling the growth direction of NWs is vital in nanotechnology applications and future optoelectronic devices. In an effort to address the above, we have begun studies aimed at selectively controlling the growth direction of horizont ...

15. Near-Field Vibrational Spectroscopy: Infrared and Raman Studies at High Spatial Resolution
Published: 1/1/2002
Authors: Stephan J Stranick, D B Chase, Chris A Michaels
Abstract: The ability to measure chemical bond changes on the nanometer scale is of critical importance for the characterization of catalytic materials, engineered materials and surfaces relevant to biological problems. In this paper, we will outline the deve ...

16. Modeling Illumination-Mode Near-Field Optical Microscopy of Au Nanoparticles
Published: 3/1/2001
Authors: A Liu, A Rahmani, Garnett W Bryant, Lee J Richter, Stephan J Stranick
Abstract: We present a theoretical analysis of near-field scanning optical microscopy (NSOM) images of small Au particles made in illumination mode. We model the metal-coated fiber tip as a thin disk consisting of a glass core and an aluminum coating. An ext ...

17. Chemical Imaging With Scanning Near-Field Infrared Microscopy and Spectroscopy
Published: 10/1/2000
Authors: Chris A Michaels, Lee J Richter, Richard R Cavanagh, Stephan J Stranick
Abstract: The development of a scanning near-field microscope that utilizes infrared absorption as the optical contrast mechanism is described. This instrument couples the nanoscale spatial resolution of a scanning probe microscope with the chemical specifici ...

18. Scanning Near-Field Infared Microscopy and Spectroscopy with a Broadband Laser Source
Published: 10/1/2000
Authors: Chris A Michaels, Lee J Richter, Richard R Cavanagh, Stephan J Stranick
Abstract: Near-field scanning optical microscopy (NSOM) is a powerful tool for the characterization of the optical properties of nanoscale objects, although pervasive artifacts often create difficulties in image interpretation. A three dimensional scanning NS ...

19. Scanning Near-Field Infrared Microscopy and Spectroscopy With a Broadband Laser Source
Published: 10/1/2000
Authors: Chris A Michaels, Stephan J Stranick, Lee J Richter, Richard R Cavanagh
Abstract: A scanning near-field microscopy that allows the fast acquisition of mid-infrared absorption spectra is described. The microscope couples the nanoscale spatial resolution of a scanning probe microscope with the chemical specificity of vibrational spe ...

20. Assessment of Sensitivity Advances in Near-Field Raman Spectroscopy
Published: 9/1/2000
Authors: Chris A Michaels, C EJ Dentinger, Lee J Richter, D B Chase, Richard R Cavanagh, Stephan J Stranick
Abstract: Near-field Raman spectroscopy can be used to obtain images with both chemical specificity and the subwavelength spatial resolution of near-field scanning optical microscopy (NSOM). In the absence of signal intensification factors, such as surface en ...
