Tridyn-binary collision simulation of atomic collisions and dynamic composition changes in solids

Abstract
A computer program is described which treats the slowing down of ions in solids, and the associated formation of recoil atom cascades in the binary collision approximation. For multicomponent media, it takes into account dynamic alterations of the local composition which arise from the deposition of implanted ions and the collisional transport of target atoms. In this way, phenomena can be simulated which occur during high-fluence ion bombardment, such as implantation profiles, atomic mixing ...

Title of program: TRIDYN (VERSION 3.1)
Catalogue Id: ABFH_v1_0

Nature of problem
A beam of fast ions (energy range app. 1 eV/amu to 100 KeV/amu) entering a solid substance is slowed down and scattered due to electronic interaction and nuclear collisions. Along its path, an individual projectile may create fast recoil atoms which in turn may initiate collision cascades of moving target atoms. These may either leave the surface (be sputtered) or be deposited at a site different from their original one. Together with the projectiles being deposited in the substance, this result ...

本节描述了一种计算机程序，该程序处理固体中离子的减速现象及其在二体碰撞近似下的反冲原子级联的形成。针对多组分介质，该程序考虑了由植入离子的沉积和目标原子的碰撞输运引起的局部组成的动态变化。通过这种方式，可以模拟在高通量离子轰击过程中发生的现象，例如植入剖面、原子混合等。

程序名称：TRIDYN（版本 3.1）
目录编号：ABFH_v1_0

问题性质：高速离子束（能量范围为约 1 eV/amu 至 100 KeV/amu）进入固体物质时，由于电子相互作用和核碰撞而减速并散射。在其路径上，单个投射粒子可能产生快速反冲原子，这些原子随后可能引发移动目标原子的碰撞级联。这些原子可能离开表面（被溅射）或沉积在与其原始位置不同的地方。与沉积在物质中的投射粒子一起，这导致的结果...
