Abstract

We measured step velocity Vstep in the <110> direction of two dimensional islands on the {110} faces of tetragonal lysozyme crystals under high pressure, and calculated step kinetic coefficients βstep. Vstep and βstep decreased with increasing pressure. The decrease in βstep indicates the increase in activation energy of the crystallization εkink or the mean distance between kinks on the step λ.
