Crystal in physics
WebWe investigate analytically and computationally the dynamics of 2D needle crystal growth from the melt in a narrow channel. Our analytical theory predicts that, in the low supersaturation limit, the growth velocity V decreases in time t as a power law V ∼ t − 2 / 3 , which we validate by phase-field and dendritic-needle-network simulations. WebAbstract. A set of experimental dichroic order parameters ranging from ca. +0.66 to −0.22 was obtained by recording polarized UV-visible absorption spectra from aligned samples …
