Thermally induced interface chemistry in Mo/B4C/Si/B4C multilayered films [PDF]

, 2012
B4C diffusion barrier layers are often introduced into Mo/Si multilayered films for enhancement of thermal stability. We observe that such multilayered films exhibit both period expansion and period compaction upon annealing at temperatures below 300 °C,
