Laser Modification

ABSTRACTScanning tunneling microscopy has been used to document changes in the nanometer-scale morphology of the basal plane of highly oriented pyrolytic graphite after exposure to 7 ns, 1064 nm laser.pulses in air. Surface modification was visible at fluences far below those that produce melting. Damage appears first on step edges and consists of exfoliation of graphite layers and recession of steps through removal of mono- or multilayer patches.

Ambient Exposure

The three-dimensional shape relaxation of gold nanostructures was studied by scanning tunneling microscopy in real time and at ambient conditions. The nanostructures were fabricated on a Au(100) single crystal by a two step-process: electrochemical etching to produced a rough surface, followed by thermal annealing. The nanostructures can be described as mounds having small semicircular facets that shrink in time, peeling away layer by layer as a result of the sudden temperature change and evolving towards thermodynamic equilibrium. A model developed by Uwaha is used to describe the dynamic evolution of the peeling layers, where good agreement was found despite the presence of adsorbates due to ambient exposure.
