论文摘要
使用原子计算机模拟，我们确定了氧化物玻璃的熔体形成（MS）和断裂表面（FS）的粗糙度和地形特征。我们发现，冷冻毛细血管波理论很好地描述了MS的地形。 FS比MS强大，并且很大程度上取决于玻璃成分。与实验中发现的幂律相反，FS的高度高度相关函数显示出意外的对数依赖性。因此，我们得出的结论是，长度尺度小于10 nm fs不是自我伴随分形。
Using atomistic computer simulations we determine the roughness and topographical features of melt-formed (MS) and fracture surfaces (FS) of oxide glasses. We find that the topography of the MS is described well by the frozen capillary wave theory. The FS are significant rougher than the MS and depend strongly on glass composition. The height-height correlation function for the FS shows an unexpected logarithmic dependence on distance, in contrast to the power-law found in experiments. We thus conclude that on length scales less than 10 nm FS are not self-affine fractals.
