Team Studying Melting in Polycrystalline Gold Thin Films

Caption

Brookhaven Lab physicists (from left to right) Ian Robinson, Tadesse Assefa, Ming Lu, Emil Bozin, and Simon Billinge at the Center for Functional Nanomaterials cleanroom, where they fabricated polycrystalline gold films of 50-, 100-, and 300-nanometer thickness. The team used time-resolved x-ray diffraction to understand the mechanism of melting in films excited by a laser that emits optical pulses with an extremely short duration. Their analysis of the X-ray diffraction images revealed that melting (induced by the laser) starts in one place and then moves into another location.
