Microscope:
RHK UHV 7500

Controls:
SPM 1000 Control System

Description :
Large regularly shaped islands on air-cleaved mica surfaces after degassing in UHV at 473 K for 14 h recorded in the constant detuning mode. NC-AFM images recorded in the constant detuning mode. The profiles shown below the images are cross-sections taken along the indicated lines. (a) Island of 1.7 nm height with regular shape. Image taken at a detuning of -7.3 Hz and a bias voltage of 0 V. (b) Island of 5 nm height. The extended bright lobes in the centre of this structure are a scanning artefact. Image taken at a detuning of -4.0 Hz and a bias voltage of -1.3 V. (c) Zoom into the structure marked by the square in frame (b) revealing three terraces. Image taken at a detuning of -22.1 Hz and a bias voltage of 0 V.
