THE STRUCTURES OP DECAGONAL AND QUASICRYSTALLINE PHASES WITH 1.2 nm AND 1.6 nm PERIODS, STUDIED BY HIGH-RESOLUTION ELECTRON MICROSCOPY

摘要

Our recent high-resolution electron microscopic studies for decagonal quasicrystals with 1.2 nm and 1.6 nm periods and their related crystalline phases are reviewed. The structures of the quasicrystals and crystalline phases are systematically interpreted in terms of aperiodic and periodic tilings formed with definite linkages of fundamental atom columns with pentagonal or decagonal symmetry.
