Calcite Screw Dislocation Under Continuous CaCO3 Growth-etch Solution

This movie was taken on the Cypher ES Environmental AFM using blueDrive photothermal excitation.

The freshly cleaved calcite sample was imaged under continuous flow (~3uL/s) of growth and etch solution. The pH of the solution was varied to control the growth/etch rate.
