On crystals containing growth defects, the “burst-like growth” mode, i.e., a sharp acceleration of the growth of facets, has been implemented. This has confirmed the hypothesis that the same physical mechanisms are responsible for the transition of facets in the state of anomalously rapid growth at high and low temperatures. It has been found that the transition from the fast to slow kinetics of crystal facet growth is stepwise. It has been established that the relaxation of the kinetic coefficient of growth is similar to the relaxation of the elastic moduli of the crystal after the fast growth stage. The kinetic coefficients of crystal growth at fast and slow growth stages have been determined.

在亚稳态液体中成核的4 He晶体上的“爆发状生长”模式的观察

在含有生长缺陷的晶体上,已经实现了“爆发状生长”模式,即刻面生长的急剧加速。这已经证实了这样一个假设:在高温和低温下,异常状态下快速增长的状态下,小平面的过渡是由相同的物理机制造成的。已经发现,从晶体刻面生长的快速动力学到缓慢动力学的过渡是逐步的。已经确定,生长的动力学系数的松弛类似于快速生长阶段之后晶体的弹性模量的松弛。已经确定了快速和慢速生长阶段晶体生长的动力学系数。
