Dr. Hongzhou Zhang

Dr Hongzhou Zhang received a BSc degree and an MSc degree in physics from Peking University (China) and a PhD in applied physics from Rice University (USA). From 2002 to 2004 he had a post-doctoral position at the National Laboratory of Mesoscopic Physics and Electron Microscopy (Peking University, China), where he conducted research into the application of electron microscopy to one-dimensional nanostructures. In 2004 he became a research fellow of the Electronic Materials Engineering Department at the Australian National University (Australia). During this period, he synthesized and characterized BN nanostructures. In 2009 he moved to Dublin and joined CRANN as a Principal Investigator and holds a Stokes Lecturer position in the School of Physics, Trinity College Dublin

Our primary research at Trinity focuses on developing and utilizing ultramicroscopy methodologies such as helion-ion microscopy and electron micrscopy. Specifically, our current research includes electron/helium ion diffraction and imaging, structural defects of magnetic and electronic materials(e.g., interfaces, domain/grain boundaries, stacking faults,...), in-situ microscopy, and e-beam/ion beam etching/depositoin/lithography. The major object is to further understand the interaction between electron/helium ion beam with materials and thus to develop methodologies for material characterization and manipulation. Our research also includes the study of the growth-structure-property relationship of nanostructures by employing ultramicroscopy techniques. This covers the synthesis of nanoscaled crystals, advanced nanoscale composition and structure analysis (scanning electron microscopy, transmission electron microscopy, and electron energy loss spectroscopy etc.), luminescence of nanostructures, and field emission of nanostructures. We have a special interest in experimental study of doping of one-dimensional nanomaterials, in-situ observation of dopant migration and its significance for fabrication and application of novel nanodevices.
