讲座简介:

Helium-ion microscope (HIM) is a recently developed tool [1] in the family of charged-beam microscope, which is set to become a key enabling technology for the future of nanoscience. This talk discussed the fundamental aspects of the tool with an objective of highlighting its unprecedented abilities in nanoscale modification. Recent progress in this field will be introduced, particularly the applications of the HIM in nanoscale device fabrication and two-dimensional materials functionalization, for example, superconductor quantum device[2], plasmonic nanoatennas[3], MoS2 nanoribbon structuring [4], etc. The potential of the tool and its future development will also be discussed.

Speaker’s Biography

Dr. Zhang received his PhD in Applied Physics at Rice University (USA) in 2002. He held a government postdoctoral fellowship at Peking University, China (2002-2004). In 2004 he became a research fellow in the electronic materials engineering department at the Australian National University. He then joined School of Physics at Trinity College Dublin as a SFI Stokes Lecturer in 2009. He was elected as a Fellow of Trinity College in 2014. He is a Principal Investigator at the Centre for Research on Adaptive Nanostructures and Nanodevices. His research is concerned with controllable synthesis and modification of low-dimensional nanostructures with the objective of generating specific physical properties. His recent research activities are primarily focused on developing and applying new electron/ion beam methodologies for nanoscale characterization and modification. He has published > 130 peer-reviewed papers in physics and nanoscience, mostly in high impact journals (e.g., Applied Physics Letters, Advanced Materials, Nanoletters, Small, etc.). He is a pioneering researcher and a recognised leader in the field of helium-ion microscopy (HIM). He is a member of the executive committee of the Microscopy Society of Ireland and a reviewer for several international funding agencies and academic journals.
