| Outline of Final Research Achievements |
In order to understand the mechanism of friction through atomic to micrometer scales, various single crystal surfaces were scrathced with a saphire stylus in different directions. Observation of wear patterns formed using optical and atomic force microscopies revealed the mechanisms of activation of plastic deformation modes including slip, cleavage and twinning, depending upon the direction and the strength of applied load, and the location relative to the position of the stylus.
To understand why crystals grow in different polyhedral forms depending upon environments, stabilities of crystal faces were compared by observing micro-sized etch pits formed in dissolution experiments. Crystal shapes of nano- and micro-crystals were controlled by the addition of functional molecules which adsorb selectively upon specific crystal faces.
