Abstract: From a quite long time,the research on crystal growth mechanism has been mainly based on the indirect theoretical analysis.Atomic force microscope(AFM) is a new and effective tool for the research of crystal growth mechanism.The atomic resolution and the ability of working in liquid make it possible to observe the interfaces of crystal growth directly.There are some new discoveries on the crystal growth mechanism based on the AFM study so far.The BCF model about smooth interface growth kinetics and the C-V model about impurity stopping step have been collided with the AFM study results.Some new contents have been found on the influence of structure anisotropy on crystal growth.The growth mechanism of macromolecular crystals in faced with a wonderful developing opportunity.It is shown that there will be an important breakthrough in crystal growth theory.
