    • Analysis of Scanned Probe Images for Magnetic Focusing in Graphene 

      Bhandari, Sagar; Lee, Gil-Ho; Kim, Philip; Westervelt, Robert M. (Springer Nature, 2017)
      We have used cooled scanning probe microscopy (SPM) to study electron motion in nanoscale devices. The charged tip of the microscope was raster-scanned at constant height above the surface as the conductance of the device ...
    • Imaging Cyclotron Orbits of Electrons in Graphene 

      Bhandari, Sagar; Lee, Gil-Ho; Klales, Anna Margaret; Watanabe, Kenji; Taniguchi, Takashi; Heller, Eric J.; Kim, Philip; Westervelt, Robert M. (American Chemical Society (ACS), 2016)
      Electrons in graphene can travel for several microns without scattering at low temperatures, and their motion becomes ballistic, following classical trajectories. When a magnetic field B is applied perpendicular to the ...
    • Inducing superconducting correlation in quantum Hall edge states 

      Lee, Gil-Ho; Huang, Katie; Efetov, Dmitri K.; Wei, Di Sonia; Hart, Sean; Taniguchi, Takashi; Watanabe, Kenji; Yacoby, Amir; Kim, Philip (Springer Nature, 2017)
      The quantum Hall (QH) effect supports a set of chiral edge states at the boundary of a two-dimensional system. A superconductor (SC) contacting these states can provide correlations of the quasiparticles in the dissipationless ...
    • Ultimately short ballistic vertical graphene Josephson junctions 

      Lee, Gil-Ho; Kim, Sol; Jhi, Seung-Hoon; Lee, Hu-Jong (Nature Pub. Group, 2015)
      Much efforts have been made for the realization of hybrid Josephson junctions incorporating various materials for the fundamental studies of exotic physical phenomena as well as the applications to superconducting quantum ...
