'High Resolution' Is Often Sought in SEM Imaging, But Establishing Visibility May Be the Challenge: Always Ask "What Might I Be Missing?"

Dale E. Newbury

Abstract

The visibility of objects in scanning electron microscope (SEM) images is limited by random noise in the signal, and a relation can be established between the contrast produced by an object relative to local background and the instrument parameters: electron detector efficiency; beam current, and pixel dwell time.
