ELECTRON

Each of the charge sensing methods described above may be applied to a range of systems. As mentioned above, we are working to use our TDCS method on high temperature superconductors. We are also using charging methods to study chemical potential shifts in novel electronic systems formed at the interface between two polar oxides, and we are applying the SCA imaging to study graphene. The methods each probe physical quantities that are inaccessible to more conventional methods. As a result, we have achieved a long record of discovery of unexpected phenomena that I believe will continue as we advance our experimental methods and apply them to new material systems... We have developed methods of wide bandwidth, high fidelity, and very sensitive charge sensing to perform some unique and fundamental measurements on these low dimensional electronic systems. These capabilities have permitted us to make some basic queries about interacting electronic systems.
