41. Theta-like specimen to determine tensile strength at the micro-scale
Published: 3/10/2010
Authors: Michael S. Gaither, Frank W DelRio, Richard Swift Gates, Edwin R. Fuller, Robert Francis Cook
Abstract: Micro- and nano-electromechanical systems are typically formed via lithographic and etching processes that leave residual surface features, stresses, and chemistry that ultimately control component strength and device reliability. Here, we describe ...

42. The Nanomechanical Properties of Thin Film of Type I Collagen Fibrils
Published: 3/2/2010
Authors: Koo-Hyun Chung, Kiran Bhadriraju, Tighe Spurlin, Robert Francis Cook, Anne L Plant
Abstract: Cells sense and respond to the mechanical properties of the substrate to which they adhere. Matrices composed of collagen have been an important experimental system to study cell responses to the stiffness of the extracellular matrix. We had previo ...

43. Nanomechanical Measurements and Tools
Published: 2/23/2010
Author: Robert Francis Cook
Abstract: Nanotechnology provides great opportunities for the development of advanced devices with enormous quality-of-life and economic benefits, with applications ranging from biomedical implantable actuators to environmental toxin detectors to infrastructur ...

44. Size Measurement of Nanoparticles using Atomic Force Microscopy
Published: 10/1/2009
Authors: Jaroslaw Grobelny, Frank W DelRio, Pradeep Narayanan Namboodiri, Doo-In Kim, Vincent A Hackley, Robert Francis Cook
Abstract: In this assay protocol, procedures for dispersing gold nanoparticles on various surfaces such that they are suitable for imaging and height measurement via intermittent contact mode AFM are first described. The procedures for AFM calibration and ope ...

45. Elastic modulus of low-k dielectric thin films measured by load-dependent contact-resonance atomic force microscopy
Published: 9/14/2009
Authors: Gheorghe Stan, Sean King, Robert Francis Cook
Abstract: Correlated force and contact-resonance versus displacement responses have been resolved using load-dependent contact-resonance atomic force microscopy (AFM) to determine the elastic modulus of low-k dielectric thin films. The measurements consisted ...

46. Stress-Intensity Factor and Toughness Measurement at the Nanoscale using Confocal Raman Microscopy
Published: 7/12/2009
Authors: Robert Francis Cook, Yvonne Beatrice Gerbig, Mark D Vaudin, Jeroen Schoenmaker, Stephan J Stranick
Abstract: A confocal Raman microscopy technique is presented that allows stress measurement at the nanoscale, which in turn enables measurement of stress-intensity factors (SIF) at crack tips and thus toughness to be estimated. Peak-fitting and super-resolutio ...

47. Fracture toughness measurement of thin nanoporous films on stiff substrates
Published: 6/15/2009
Authors: Dylan Morris, Robert Francis Cook
Abstract: Nanoporous low-dielectric-constant films constitute a class of materials that are plagued by fracture concerns and are not amenable to traditional fracture toughness measurement techniques. An indentation fracture toughness measurement technique has ...

48. Torsional spring constant measurement of a T-shaped atomic force microscope cantilever
Published: 6/1/2009
Authors: Mark Reitsma, Richard Swift Gates, Robert Francis Cook
Abstract: We present a microfabricated atomic force microscope (AFM) cantilever that is used to calibrate AFM friction data. The T-shaped lateral force cantilever is equipped with lever-arms that facilitate the application of normal and lateral forces, all ...

49. Elastic and adhesive properties of alkanethiol self-assembled monolayers on gold
Published: 3/30/2009
Authors: Frank W DelRio, Cherno Jaye, Daniel A Fischer, Robert Francis Cook
Abstract: Elastic and adhesive properties of alkanethiol (CH3(CH2)n 1SH) self-assembled monolayers on gold are investigated by atomic force microscopy and correlated with surface structure via near edge x-ray absorption fine structure spectroscopy. As the cha ...

50. Effect of crystallographic orientation on phase transformations during indentation of silicon
Published: 3/9/2009
Authors: Yvonne Beatrice Gerbig, Dylan Morris, Stephan J Stranick, Mark D Vaudin, Robert Francis Cook
Abstract: In a statistical nanoindentation study using a spherical probe, the effect of crystallographic orientation on the phase transformation of silicon (Si) was investigated. The presence and pressure at which events associated with phase transformation oc ...
