PHASE SELECTION IN CRYSTAL MONOLAYER OF LOW MOLECULAR WEIGHT POLYETHYLENE OXIDE) ON MICA SURFACE
Though metastable phases presented in processing a wide variety of materials are of great practical importance, a little is known of their phase selection mechanisms. Solidification to nonequilibrium phases has been observed in freezing of undercooled liquids, crystallization of oxide and metallic metals, etc., but detail experimental results for quantities characterizing these kinetic processes are rare. Due to the experimental difficulties, remarkable efforts have been made to develop both theoretical and numerical methods to identify main features of such complex systems far from equilibrium. In order to verify the fruitful predictions, a comparison of experimental and theoretical results has to be carried out. Here, we report our experimental observations on crystallization of monolayer crystals on mica surface, which may be well explained by the theory proposed by Grandsy and Oxtoby1 (GO).
