The primary focus of the Mesoscopic Physics Group is the study of small structures and devices; not small on the atomic scale, but small enough that coherent quantum effects can be observed. This requires that these devices and structures be typically less than a micron in size, with the smallest features on the order of 10s of nanometers. In order to fabricate these devices, we employ the techniques of nanolithography, using the electron-beam writer as well as the large range of fabrication equipment in our group. This allows us to make complex, multilevel devices that combine normal metals, superconductors, ferromagnets and more exotic materials to study the interaction between fundamental phenomena on the nanoscale. Some examples of such devices are shown here.
