Emergent behavior in thin film heterostructures
Thin film heterostructures provide unique platforms for tailoring electronic states. The ability to manipulate a material's electronic ground state via strain, confinement, and interface effects can be harnessed to control phenomena ranging from superconductivity, magnetism, quantum criticality, and charge/orbital order. One particularly fascinating aspect is the ability to create quantum wells inside of a variety of hosts whose carrier densities can be driven to extreme highly levels via confinement effects. The interplay between these high density quantum wells and correlation effects in a host material are an area of our particular focus. Our activities focus on exploring magnetism and orbital order in thin film heterostructures via neutron and synchrotron x-ray scattering techniques. We collaborate closely with groups such as the Stemmer group at UCSB to obtain pristine thin films for experimental study.
