Nothing is Brittle at the Nanoscale

November 15, 2007

Author(s)

Pradeep N. Namboodiri, Doo-In Kim, Jaroslaw Grobelny, T Hawa, B Henz, Michael R. Zachariah

Fracture of nanoscale contacts formed between spherical probes and flat samples is studied using an atomic force microscope (AFM) in ultra high vacuum environment. Analysis of the nonlinear elastic behavior observed during the fracture process in the force

Nanoparticle Lithography and Imaging Scanning Probe Microscopy

October 1, 2006

Author(s)

Jaroslaw Grobelny, De-Hao D. Tsai, Doo-In Kim, Pradeep N. Namboodiri, Robert F. Cook, Michael R. Zachariah

Scanning tunnelling microscopy (STM) imaging was performed on goldsurfaces with a large coverage of monodispersed silver nanoparticlessoft-landed on the surface from the gas phase. In both ambient and ultra-highvacuum conditions, STM scanning was found to

Quantification of the Meniscus Effect in Adhesion Force Measurements

February 1, 2006

Author(s)

Jaroslaw Grobelny, Pradeep N. Namboodiri, Doo-In Kim, Z C. Ying

Adhesion forces between a gold sphere and flat gold substrate are studied using atomic force microscopy in different environments. The pull-off force measured in vacuum is found to be a small fraction of that in ambient air or nitrogen atmosphere. In
