Abstract
Polishing of the parallel surfaces of an optical crystal is essentially req uired for smooth transmission of a laser beam. However, a procedure for pol ishing the (00-1) surface of a material on a molecular scale has not been r eported so far. In this paper we have proposed the nano-polishing method of organic crystals by scanning the tip of an atomic force microscope with an appropriate load depending on the surface condition. It has been demonstra ted that both the (001) and (00-1) planes of 4-dimethylamino-N-methyl-4-sti lbazolium tosylate (DAST) crystal grown by a seed-standing method can be fl attened on a molecular scale. Thus, we have successfully obtained molecular ly parallel surfaces.
