First-principles study of fracture toughness enhancement in transition metal nitrides

Due to its superior thermophysical properties, ZrN thin film has been studied as a diffusion barrier for a variety of applications. However, cracks and delamination of ZrN coating takes place because of its brittleness. To identify new diffusion barrier materials with improved fracture toughness, we...
