“…We found that unless the system is purely DL, the height of the grating decays exponentially in time, agreeing entirely with the experiments of Keeffe et al [5]. Figure 1 shows that even when ℓ = λ x and the grating amplitude is 50 steps (values comparable to the experimental ones), an exponential decay fits the step model results better than an inverse linear decay.…”

“…As a result we derive a nonlinear, fourth-order PDE for h when steps interact via nearest-neighbor repulsions, describing the combined effect of step energetics and kinetics, and surface topography; see (4.39). Possible connections of this PDE to experimental observations [24,12] of decaying surface profiles, although incomplete at the moment [29], can be useful for predicting lifetimes and other properties of surface structures.…”

“…Массоперенос при спекании может определяться раз-ными механизмами [7], среди которых внутри по-ристого слоя определяющими являются объемная и поверхностная диффузия. Изменение размера внут-ренних пор r определяется диффузионной длиной [9], но оказывается значительно ниже, чем энергия активации объемной самодиффузии в Si: 4.86 эВ [10,11]. Это говорит о смешанном механизме диффузии, обеспечивающей массоперенос при спекании.…”
