Size-Dependent Elastic Modulus and Vibration Frequency of Nanocrystals
Figure 1
Size-dependent elastic modulus and vibration frequency of Cu thin films and nanocrystals. In (6), Jmol-1 K-1 for metals [23], is the melting temperature. respectively, for (111) and (100) faces corresponding to the computational simulation [8] and continuum mechanics calculation [11] of thin films. For nanocrystalline Cu, the solid-solid interface energy Jm-2 [23], for Cu thin films, is the surface energy. Other related parameters are in Table 1.
