Abstract:
Ion beam technology using advanced ion sources and accelerators provides not only exciting physical phenomena but also processing of various advanced materials in an efficient and controlled way. Among the utilized ion beams, highly energetic (MeV-GeV) heavy ions and slow (eV-keV) highly charged ions exhibit the unique ability of fabricating surface nanostructures via single impacts in different materials.  The type, size and location of the induced modifications depends highly on ion beam parameters including electronic energy loss, nuclear energy loss, fluence, charge state, ions species, and penetration depth. 

In this talk, various aspects of ion-solid interactions as well as up-to-date applications will be presented. In addition, promising recent results on ion-induced modifications in 2D and 3D materials are introduced.

Biography:
Dr. Ayman Sherif El-Said received his Ph.D. from Heidelberg University, Germany in the field of ion-solid interaction at the GSI Helmholtz Centre for Heavy Ion Research (Germany). This is directly after obtaining the DAAD German scholarship.  He also received the Lise Meitner Fellowship from the Austrian science Fund (Austria) in 2005. This fellowship enabled him to conduct his postdoctoral research work at the Vienna University of Technology. His research stay in Vienna was extended as a senior scientist by working in the same research area, namely nanostructuring using ion beam technology. Dr. El-Said worked as experienced researcher at the Institute of Ion beam Physics and Material Research of Helmholtz-Zentrum Dresden-Rossendorf (Germany) by obtaining the Alexander von Humboldt fellowship for experienced researchers in 2009. He received the state award in Physics from the Egyptian Academy of Science and Technology in 2011. He received also recognition from KFUPM by getting the “Excellence in Research Award” in 2018. The research findings by Dr. El-Said were published in prestigious journals in physics including Phys. Rev. Lett, Phys. Rev. Appl., Phys. Rev. B, Appl. Phys. Lett…. etc. The recent research interest of Dr. El-Said is applying ion beam technology in photonic and quantum materials.
