DISLOCATIONS AS FLEXIBLE OBJECTS - INTERACTIONS AND UNBINDING TRANSITION

Author(s): HOLYST, R and VILGIS, TA
Title: DISLOCATIONS AS FLEXIBLE OBJECTS - INTERACTIONS AND UNBINDING TRANSITION
Abstract: The elastic interactions between dislocations in a finite lamellar of N layers are calculated as a function of the size of the surface tension and lamellar elastic constants. For large tension the in-plane interactions are repulsive for like and attractive for opposite ones, decaying exponentially the decay length proportional to square-root N. Their strength is proportional to square-root N. For small surface tension the interactions are attractive at large distances for like and repulsive for opposite ones. In thin films with small tension like dislocations are stabilized at finite separations square-root N), while in thick films they unbind due to forces. The unbinding transition is extremely sensitive to the surface tension and surface bending elastic constant.
