Abstract
In situ high-temperature, high resolution transmission electron microscopy (HRTEM) was performed on an Al-Cu-Co decagonal quasicrystal, to investigate thermal fluctuation of phasons. A tiling pattern constructed from the HRTE M image was analyzed in the framework of the strip-projection method. Trans itions between two local tile arrangements were observed at high temperatur e for the first time, and were shown to correspond to a thermal phason fluc tuation.
