EQUILIBRIUM SHAPES OF DROPLETS ACROSS GRAIN-BOUNDARIES

The equilibrium shape of a crystal in an infinite or a semi-infinite s ystem has been known for decades. Here, we consider shapes of droplets which straddle mio semifinite systems, joint at a planar, common boun dary, such as a grain boundary of twinned crystals. For arbitrary anis otropic surface tensions, this problem is solved, in two dimensions. S ome examples and special limits are shown. (C) 1998 Published by Elsev ier Science B.V. All rights reserved.
