The {001} surfaces of n-C 23 H 48 paraffin crystals have been investigated by ex situ alternative contact mode atomic force microscopy (AC-AFM). Although the crystals were scanned in air, without any solution present and below the melting temperature of n-C 23 H 48 , crystal growth or etching was revealed in all experiments, independently of the...
The development of (111) cleavage faces of CaF 2 upon thermal treatment is studied by atomic force microscopy (AFM). Vacuum-cleaved surfaces show the atomic periodicity of the uppermost fluorine layer. Cleavage steps have heights of about 0.32nm, corresponding to the spacing of neighboring F - -Ca 2+ -F - triple layers, or integer multiples thereof. The steps exhibit...
