Dynamic studies of crystal growth using the AFM

摘要

Recent advances in AFM atomic force microscopy technology allow direct observation of solution growth and dissolution (etching) processes important in industry and nature, and direct tests of crystal growth models. We present results of studies of calcite and quartz, including real-time, in situ observations. While both crystals experience layer growth/dissolution, calcite grows by direct addition of material to growth steps without an important contribution from surface diffusion; quartz surfaces are consistent with more traditional, BCF-type growth models. Dynamic AFM observations of growth processes may allow optimization of industrial systems.
