Effects of creep on the behavior of nanometer-scale contacts to viscoelastic materials are described from the viewpoint of the contact mechanics theory developed by Ting. The two most important effects are: (1) The time at which maximum contact area

Dynamic mechanical contacts with nanometer-to-micrometer dimensions are important in scanned probe microscopy, ultra-low load indentation, microelectromechanical systems, compact discs, etc. The response of these contacts is poorly understood if they

The film that forms spontaneously when boron oxide (B2O3) is exposed to humid air is a solid lubricant. This film is usually assumed to be boric acid (H3BO3), the stable bulk phase. We describe the nanometer-scale surface morphology, mechanical prope

The order-disorder transition at the (001) surface of a 3 at. %-Au-rich ${\mathrm{Cu}}_{3}$Au crystal has been studied using surface x-ray scattering and Auger-electron spectroscopy. ${\mathrm{Cu}}_{3}$Au is a prototypical system for ordering alloys

PMDA-ODA polyimide thin films can be formed by vapor co-deposition of the precursor molecules PMDA (pyromellitic dianhydride) and ODA (4, 4′-oxydianiline) if the resulting polyamic acid film is heated to a 473 to 573 K cure step. We have used laser
