Jessica McChesney works offsite in collaboration with Argonne National Laboratory, Advanced Photon Source.
As dimensionality of a material is reduced, the fundamental physical properties changes often resulting in new exotic properties which did not exist for the bulk. When devices are shrunk to nanometer length scales their behavior can no longer be described in terms of macroscopic parameters; instead, quantum mechanical interactions need to be taken into account. These interactions, resulting from the confinement of electrons, lead to the exotic phenomena has been observed for many nanostructures including quantized conductance, quantum well states, formation of charge/spin density waves, superconductivity, enhanced catalytic properties. My research is focused on using x-ray techniques to study the electronic properties of these quantum transport materials, in particular materials that are relevant to nanoelectronics and energy storage needs, like topological insulators, graphene, graphite intercalation compounds and self-assembled nanowires and nanoparticles.
