Combined STM/ARPES System [In development]

A new Scanning Probe Microscope (SPM) system that operates in ultrahigh vacuum and down to 1K temperatures is being designed which will enable investigation of the unusual electronic phases that emerge in these materials while ensuring the high energy resolution required to locally probe the electronic structure critically related to underlying interactions. The SPM will also be located within a magnetic field of up to 3T allowing tuning of the electronic interactions, creation of vortices in superconductors, and techniques such as spin polarized scanning tunneling microscopy (STM), magnetic force microscopy and electron paramagnetic resonance-STM that allow investigation of nanoscale magnetism. To complement the atomic scale picture revealed by SPM methods, a second, attached chamber will provide angle resolved photoemission (ARPES) capabilities. In systems where electrons are delocalized, ARPES gives direct access to the band structure that best describes the electronic states and underlies transport and other properties. With both tools applied to the same systems, a clear picture of how atomic scale structure, electronic states and magnetism connects to the macroscopic band structure, an unprecedented view of quantum materials will be revealed.  Mid 2019.
