摘要: The combination of long-time, tight-binding molecular dynamics and real-time multiresolution analysis techniques reveals the complexity small silicon interstitial defects. stability identified structures is confirmed by ab initio relaxations. majority were previously unknown, demonstrating effectiveness approach. A new, spatially extended tri-interstitial ground state structure as a probable nucleation site for larger defects may be key compact-to-extended transition.
