Abstract
Scanning tunneling microscopy (STM) in vacuum is used to study and compare individual islands of silver and gold formed from thin films of these metals on silicon. Data are processed digitally to provide detailed color images. Islands formed by low temperature anneals in air are shown to present a smooth spheroidal-like surface while the islands formed by in situevaporation onto a clear silicon (1 1 1) face present much flatter surfaces and appear as crystalline platelets. The shape of the STM probe tip is shown to affect the lateral resolution, broadening the apparent surface features. For some tip morphologies, topological artifacts are displayed in the data.
