| Research Abstract |
The amplification mechanisms of symmetry breaking in crystal growth were studied. 1) We showed, in solution growth models of various levels, chirality of crystals can be changed by simply grinding crystals if there are chiral molecular clusters that contribute to the growth of crystals. 2) With the symmetry between the upper and the lower terraces of a step, a moving atom source causes strange pattern evolution of the growing step. And the asymmetry also causes peculiar shape relaxation behavior of labyrinthine holes on a facet.
