Nanoscale intergranular films shed light on grain boundary behavior

By Eileen De Guire / May 26, 2011

During one of their studies, grain boundary researchers began with gold films broken into particles (via annealing) dispersed across a sapphire substrate. Credit: Baram, et al; Technion. Materials scientists have long recognized that grain boundaries…
