Direct observation of grain rotation-induced grain coalescence in two-dimensional colloidal crystals.
A spatially modulated laser is used to produce multiple localized thermal gradients in a colloidal sample placed above a gold surface. We use an optical microscope to observe real time dynamics of the resulting two-dimensional colloidal crystal grains and find that grain rotation-induced grain coale...
