제목 Alteration of crystal structure of bismuth confined in cylindrical nanopores
초록 Nanoscopic materials, compared to their bulk counter parts, have peculiar properties which are important in practical applications such as quantum-dot lasers and optical detectors. Among the nanostructured materials, interest in one-dimensional (1D) structures has recently begun to increase since unique studies on the anisotropic properties of such nanomaterials can be performed. In this work, the effect of nanoscopic cylindrical confinement on the crystal structures and crystallization behaviors of Bi was investigated. While the crystallites of Bi nanorods were found to have a higher orientation proportional to the degree of confinement, an alteration of the crystal orientation between electrodeposited and recrystallized Bi nanorods was observed. Thermal analysis confirmed a structural difference between the as-deposited and recrystallized nanorods and that a crystallization mechanism where nucleation determines the overall rate of crystallization occurred during recrystallization.
