The award enabled the PI to acquire a complete cryogenic system with a 9-Tesla superconducting magnet. The equipment facilitated transport experiments on topological insulators and Dirac and Weyl semimetals. These experiments resulted in several notable achievements and novel findings during the period 2013-2015. These include successful tuning of the chemical potential by liquid ion gating in Bi2Te2Seto access the n 1 Landau level, discovery of non-saturating magnetoresistance in WTe2, initial findings on the chiral anomaly in the Dirac semimetal Na3Bi. Recently, the cryogenic system has been used for Fraunhofer measurements un ferromagnet-superconducting SQUID junctions.
