Abstract

The electronic stopping cross section of Ti for light ions is measured in an energy range of 1.3–5.0 keV for H⁺, and 1.5–10.0 keV for He⁺. All measurements were performed using in-situ Time-of-Flight Low-Energy Ion Scattering (ToF-LEIS) on ultrathin Ti layers, enabling absolute energy loss measurements. Monte-Carlo simulations are used to fit the experimental spectra and to extract the stopping cross section quantitatively. The free electron gas model is applied to collect additional information on the electronic stopping of light ions in Ti. We further compare the presented experimental data with previously published experimental data, semi-empirical models, and theoretical predictions.

钛对慢速氢、氘和氦离子的实验电子阻挡截面

在 1.3-5.0 keV 和 1.5-10.0 keV 的能量范围内测量了轻离子对 Ti 的电子阻挡截面。所有测量都是在超薄钛层上使用原位飞行时间低能离子散射（ToF-LEIS）进行的，从而实现了绝对能量损失测量。蒙特卡洛模拟用于拟合实验光谱和定量提取停止截面。自由电子气体模型被用于收集钛中轻离子电子停止的额外信息。我们进一步将所提供的实验数据与之前公布的实验数据、半经验模型和理论预测进行了比较。

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.
