1. Interfacial Mechanical Properties of n-Alkylsilane Monolayers on Silicon Substrates
Published: 2/1/2013
Authors: Brian Griffith Bush, Frank W DelRio, Cherno Jaye, Daniel A Fischer, Robert Francis Cook
Abstract: The interfacial properties of n-alkylsilane self-assembled monolayers on silicon were investigated by normal force spectroscopy and lateral force measurements and correlated with molecular structure via near-edge X-ray absorption fine structure (NEXA ...

2. Indentation device for in situ Raman spectroscopic and optical studies
Published: 12/12/2012
Authors: Yvonne Beatrice Gerbig, Chris A Michaels, Aaron M Forster, John W Hettenhouser, Walter Eric Byrd, Dylan J. Morris, Robert Francis Cook
Abstract: Instrumented indentation is a widely used technique to study the mechanical behavior of materials at small length scales and thus has been exploited in particular for metals, ceramics, glasses, and polymers. Mechanical tests of bulk materials, micros ...

3. In situ observation of the indentation-induced phase transformation of silicon thin films
Published: 3/5/2012
Authors: Yvonne Beatrice Gerbig, Chris A Michaels, Aaron M Forster, Robert Francis Cook
Abstract: Indentation-induced phase transformation processes were studied by in situ Raman microspectroscopy of the deformed contact region of silicon on sapphire samples during contact loading and unloading. During loading, the formation of Si-II and another ...

4. Nanomechanical properties of polyethylene glycol brushes on gold substrates
Published: 2/15/2012
Authors: Gheorghe Stan, Frank W DelRio, Robert I MacCuspie, Robert Francis Cook
Abstract: Brushes of polyethylene glycol (PEG) were directly anchored onto bare gold substrates in solution. The nucleation kinetics of PEG binding were investigated successively in solution and dry air using atomic force microscopy (AFM) imaging. In additio ...

5. Deformation and fracture of single-crystal silicon theta-like specimens
Published: 10/28/2011
Authors: Michael S. Gaither, Frank W DelRio, Richard Swift Gates, Robert Francis Cook
Abstract: Miniaturized test specimens of single-crystal silicon, fabricated by lithography and deep reactive ion etching (DRIE), were used to measure deformation and fracture properties at the micro scale. Two specimen geometries, both in the form of a Greek l ...

6. Micro-scale measurement and modeling of stress in silicon surrounding a tungsten-filled through-silicon via
Published: 10/11/2011
Authors: Ryan P. Koseski, William A Osborn, Stephan J Stranick, Frank W DelRio, Mark D Vaudin, Thuy Dao, Vance H. Adams, Robert Francis Cook
Abstract: The stress in silicon surrounding a tungsten-filled through-silicon via (TSV) is measured using confocal Raman microscopy line scans across the TSV both before and after etch removal of an oxide stack used as a mask to define the TSV during fabricati ...

7. Structure-property relationships for methyl-terminated alkyl self-assembled monolayers
Published: 7/20/2011
Authors: Frank W DelRio, Dave Rampulla, Cherno Jaye, Gheorghe Stan, Richard Swift Gates, Daniel A Fischer, Robert Francis Cook
Abstract: Structure-property relationships for methyl-terminated alkyl self-assembled monolayers (SAMs) are developed using near-edge X-ray absorption fine structure spectroscopy (NEXAFS) and atomic force microscopy (AFM). NEXAFS C K-edge spectra are used to ...

8. Direct observation of phase transformation anisotropy in indented silicon using confocal Raman microscopy
Published: 5/31/2011
Authors: Yvonne Beatrice Gerbig, Stephan J Stranick, Robert Francis Cook
Abstract: The theoretically-predicted anisotropic nature of the indentation phase transformation in silicon (Si) is observed directly in experiments using hyperspectral, confocal Raman microscopy. The anisotropy is reflected in the two-dimensional distribution ...

9. Size Measurement of Nanoparticles using Atomic Force Microscopy
Published: 1/1/2011
Authors: Jaroslaw Grobelny, Frank W DelRio, Pradeep Narayanan Namboodiri, Doo-In Kim, Vincent A Hackley, Robert Francis Cook
Abstract: This chapter outlines procedures for sample preparation and the determination of nanoparticle size using atomic force microscopy (AFM). To start, procedures for dispersing gold nanoparticles on various surfaces such that they are suitable for imagin ...

10. Advanced Nanoscale Elastic Property Measurement by Contact-Resonance Atomic Force Microscopy
Published: 6/23/2010
Authors: Gheorghe Stan, Robert Francis Cook
Abstract: In atomic force microscopy (AFM)-based techniques, material information (topography, mechanical, electrical, magnetic, etc.) is retrieved from the nanoscale interaction between the AFM tip and the material probed. As the size of the apex of the AFM ...
