Amorphization of Ge nanocrystals embedded in amorphous silica under ion irradiation
One of the key reasons why nanoscale materials behave differently from their bulk counterparts is that a large fraction of atoms reside at surfaces or interfaces. For instance, the melting point, hardness and even crystal structure of a nanocrystal can be dramatically different from that of the same element or compound in its conventional phase. Of particular interest from an ion-beam modification point of view is how much the structural transformations induced by energetic ions in nanocrystals...[Show more]
