摘要

应用泊松过程和蒙特卡罗方法模拟了具有有限寿命的离子轨迹在氧化物中的重叠效应。通过离子轨道重叠，预测了缺陷区的纳米尺度分布。二维分布和缺陷区总分数与离子轨迹寿命和离子通量密切相关。本文的模拟方法将为理解轨道重叠对高温高能离子辐照氧化物的影响以及由此产生的由缺陷区和非缺陷区组成的纳米结构提供有用的信息。

Computer simulation for the overlapping of ion tracks with finite lifetimes

The Poisson process and the Monte Carlo method were applied to simulate the overlapping effects of ion tracks having a finite lifetime in oxides. As a result, nanometer-scaled distributions of defective areas by the ion-track overlapping were predicted. The two-dimensional distributions and the total fraction of defective areas strongly depend on the ion track lifetime and the ion flux. The present simulation method will give a useful information for understanding the effect of the track overlapping on oxides irradiated with high-energy ions at elevated temperatures and the resulting nanostructures consisting of defective and non-defective areas.

期刊介绍： Section B of Nuclear Instruments and Methods in Physics Research covers all aspects of the interaction of energetic beams with atoms, molecules and aggregate forms of matter. This includes ion beam analysis and ion beam modification of materials as well as basic data of importance for these studies. Topics of general interest include: atomic collisions in solids, particle channelling, all aspects of collision cascades, the modification of materials by energetic beams, ion implantation, irradiation - induced changes in materials, the physics and chemistry of beam interactions and the analysis of materials by all forms of energetic radiation. Modification by ion, laser and electron beams for the study of electronic materials, metals, ceramics, insulators, polymers and other important and new materials systems are included. Related studies, such as the application of ion beam analysis to biological, archaeological and geological samples as well as applications to solve problems in planetary science are also welcome. Energetic beams of interest include atomic and molecular ions, neutrons, positrons and muons, plasmas directed at surfaces, electron and photon beams, including laser treated surfaces and studies of solids by photon radiation from rotating anodes, synchrotrons, etc. In addition, the interaction between various forms of radiation and radiation-induced deposition processes are relevant.
