SYSTEM AND METHOD TO MEASURE NANO-SCALE STRESS AND STRAIN IN MATERIALS

摘要

A system for measuring stress and strain in a sample is provided. The system includes a sample holder operable to support the sample; a stress inducing assembly operable to apply force to a selected location on the sample to deform the sample by a selected distance in a range from about 0.1 angstrom to about a millimeter; and an interferometer operable to determine a surface topography of the deformed sample at a resolution in a range from about 0.1 angstrom to about a micron.
