摘要

本文综述了冰融生长的阶梯聚束不稳定性(SBI)的研究进展,这是一种由与晶体生长动力学相关的基本阶梯流自组织驱动的界面不稳定性。借助先进的光学显微镜和双光束干涉仪,我们实现了对SBI时空动态的定量原位观测。这使我们能够在分步相互作用的水平上检查SBI的起源。我们的发现为理解冰晶生长之外的熔体生长的一般机制提供了重要的线索,不可分割地涉及几个广泛的研究领域,包括低温生物学,地球物理和材料分支。

Step-bunching Instability of Growing Interfaces between Ice and Supercooled Water
We review our recent study on step-bunching instability (SBI) of ice melt growth, one of the interfacial instabilities driven by self-organization of elementary step flow associated with crystal growth dynamics. With the aid of an advanced optical microscope and its combination with a two-beam interferometer, we realized quantitative in situ observations of the spatiotemporal dynamics of the SBI. This enables us to examine the origin of the SBI at the level of the step–step interaction. Our finding offers a significant clue to understanding the general mechanism of melt growth beyond ice-crystal growth, inseparably involving several broad research fields, including cryobiological, geophysical, and material branches.
