摘要

高迁移率的人群在晶格中以亚音速甚至超音速的速度移动，伴随着质量和能量的传递。本文研究了超音速1 -和2 -质子与钨晶格中点缺陷之间的相互作用。分子动力学模拟表明，在最靠近人群运动路径的行上存在点缺陷，严重影响人群运动。发现超声速2 -聚砜的质量和能量传递比1 -聚砜更有效。

Interaction of supersonic crowdions with point defects in BCC tungsten: molecular dynamics simulation

High mobility crowdions move in the lattice with subsonic and even supersonic velocity with the mass and energy transfer. This work studies the interaction between supersonic 1‑ and 2‑crowdions with point defects in the tungsten crystal lattice. Molecular dynamics simulation shows that the presence of point defects in the row nearest to the crowdion motion path, strongly affects the crowdion dynamics. The mass and energy transfer of supersonic 2‑crowdion is found to be more effective than that of the 1‑crowdion.
