Correlated Electrons at the Nanoscale

The Hoffman lab uses novel high resolution scanning probe techniques to understand and control the electronic and magnetic properties of exotic materials. We have designed and constructed three low-temperature microscopes to investigate a wide range of materials pictured below.
