U.S.-Czech Materials Research on Electronic Excitations in Solids During Atomic Scattering and Sputtering

这个美国-捷克材料研究项目由加州大学河滨分校的Jory Yarmoff和布拉格捷克无线电工程与电子研究所的Zeenek Sroubek共同完成，将重点研究粒子轰击在固体中引起的电子激发过程的物理特性。工作将包括散射离子能谱、中性组分和角分布的测量，以及低能粒子散射和溅射过程中相关电子发射的测量。研究人员将考虑金属、半导体和绝缘体中的这些激发，并利用理论分析，包括使用簇和伪势的分子动力学，以及完整的量子力学模型。结果在现代粒子束技术中具有潜在的意义。材料研究项目通过使美国和东欧的专家在共同感兴趣和能力强的领域结合互补的人才和共享研究资源，实现了推进科学知识的计划目标。?？

INT 9600473 Yarmoff This U.S.-Czech materials research project between Jory Yarmoff of the University of California, Riverside, and Zeenek Sroubek of the Czech Institute of Radio Engineering and Electronics, Prague, will feature investigations of the physics of electronic excitation processes induced in solids by particle bombardment. Efforts will involve measurements of the scattered ion energy spectra, neutral fractions, and angular distributions, along with measurements of the associated electron emissions during low energy particle scattering and sputtering. The researchers will consider these excitations in metals, semiconductors and insulators and draw upon theoretical analyses including molecular dynamics with the use of clusters and pseudopotentials, as well as complete quantum mechanical models. Results have potential bearing in modern particle-beam technologies. The project in material research fulfills the program objective of advancing scientific knowledge by enabling experts in the United States and Eastern Europe to combine complementary talents and share research resources in areas of strong mutual interest and competence. ??
