个人简介

Cyrus F. Hirjibehedin is a Reader, the UK equivalent of an Associate Professor, in the London Centre for Nanotechnology, Department of Physics & Astronomy, and Department of Chemistry at University College London (UCL). His group's research is focused on understanding the electronic and magnetic properties of nanometer-scale structures and exploring their potential applications in future paradigms of information processing, data storage, and sensing. The primary tools that he uses for his research are low-temperature scanning tunneling microscopes, some of which operate in high magnetic fields. These systems are able to image, manipulate, and probe structures on surfaces at the scale of individual atoms. Dr Hirjibehedin received a B.S. in both Physics and Computer Science from Stanford University in 1997, after which he earned a Ph.D. in Physics from Columbia University in 2004. His dissertation research – conducted at both Columbia and Bell Labs, Lucent Technologies under the guidance of Professor Aron Pinczuk – was a study of novel interaction effects in low dimensional electron systems formed in semiconductor quantum structures. In 2004, Dr Hirjibehedin became a postdoctoral Research Staff Member at IBM’s Almaden Research Center in the Low-Temperature Scanning Tunneling Microscopy Group. Working with Drs. Don Eigler and Andreas Heinrich, he used the atom-manipulation and spin-excitation-spectroscopy capabilities of a low-temperature high-field scanning tunneling microscope to study the onset of cooperative magnetic behavior in atomically-precise low-dimensional structures.
