| Research Abstract |
To realize the mass fabrication of various metallic micro/nano materials using stress migration (SM), the effect of thermal control including thermal cycle and atmosphere cooling was investigated systematically by carrying out a series of annealing experiments on different metallic thin films samples. The investigation on the suitable condition of thermal control for effective atomic diffusion and discharge indicates that the induced promotion of both atomic mobility and driving force can increase the absolute value of the atomic flux divergence and accelerate SM, which makes a significant contribution to mass fabrication of various metallic micro/nano materials.
