Course Objectives

This course is intended to provide graduate level engineers and scientist with a basic understanding of surface metrology. Metrology is compactly defined by the Oxford English Dictionary as a) A system or series of measures b) the science of weights and measures; thus, surface metrology is the science of measuring surfaces.

Over the last decade numerous technological advances have made it possible to measure and study surfaces at increasingly greater levels of resolution and accuracy (nm size length scales). There exist a conceptual unity between these atomic scale measurements and the meter size measurements made by surveyors and Geomaticist (a nine order of magnitude length scale difference). The course is divided into three distinct portions: (1) measuring techniques and the equipment (2) the mathematics and science of surface characterization (3) The causes and impacts of roughness. Engineers and scientist will be able to collect and characterize surface roughness data, as well as interpret and describe its impacts on performance.
