Fast Scanning of HF Etched Mica
Closed loop AC Mode image in air of atomic steps on HF-etched Mica taken with the Cypher AFM using a 10µm cantilever with a resonance frequency of 4.6 MHz. 40Hz line rate. 512 x 512 pixels. Video is real time (13 seconds per frame). Scan speed starts at 230µm/sec at a scan range of 2.35µm and then zooms to 1.35µm at a scan speed of 132µm/sec. Imaging of etched mica at these rates was first publicly shown at the MRS Meeting in November 2008.
