Dr. Ben Warner, Postdoctoral Researcher

I am currently a Postdoctoral Fellow at in the London Centre for Nanotechnology at UCL. I graduated from the University of Oxford with a MSci in Physics in 2009 and then moved to the LCN to work in the group of Cyrus F. Hirjibehedin, where I completed my PhD in 2014. In our lab, we use scanning tunnelling microscope to look at single atoms and molecules. This is only possible due to the amazing effects that occur on the atomic scale due to a quantum mechanics.  My research aims to exploit these effects to allow for the creation of novel devices that are based on a single molecule. Recently we have shown a new way to use a single molecule as a magnetic field sensor. In the study, which was published in Nature Nanotechnology, we showed how magnetism can be used to manipulate the way electricity flows through a single molecule, a key step that could enable the development of magnetic field sensors for hard drives that are a tiny fraction of their present size.
