The rigidity of carbon replicas in relation to surface topography

Abstract

The determination of relative surface elevations is of considerable importance in, for example, the study of slip processes in metals, where glide distances may range from a few Å to several

thousand Å (1). At present the most versatile technique in electron microscopy for determining fine scale features of surface topography is the stereo method, and expressions have been developed that relate the parallax in the micrograph to relative surface elevation (2, 3). An analysis of the importance of various intrinsic sources of error in stereomicroscopy has been reported elsewhere (3). The present communication outlines an additional uncertainty arising from lack of stiffness in the replica.
