Equipment
Our lab has extensive capabilities for growth and characterization of new materials. For growth systems, we specialize in thin film growth. We have a UHV e-beam evaporator capable of epitaxy at a pressure of 10-10 Torr, a state-of-the-art sputtering system similar those used in industry, a thermal evaporator, and an evaporator with in-situ resistivity capabilities.
Lab
For characterizing our films, we have several systems capable of magnetic and magneto-transport measurements. A Quantum Design MPMS Squid magnetometer and a LakeShore VSM measure magnetization, including vector magnetization. Several He-4 probes and a He-3 probe, along with both bore and split-coil superconducting magnets allow us to measure magnetoresistance and Hall effect in multiple geometries at a range of temperatures. In addition, our novel specific heat measurement capability can be used with these magnets to study the effect of magnetic field on the specific heat.

We also take advantage of the many great resources available to us here at Berkeley and through our collaborators. We have access to x-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Rutherford back-scattering (RBS), Raman spectroscopy, infrared spectroscopy, and x-ray absorption spectroscopy (XAS). These measurements allow us to better understand the new materials we are studying.
