    • Correlated Electron States in Coupled Graphene Double-Layer Heterostructures 

      Liu, Xiaomeng (2019-01-16)
      Graphene have grown to be a major experimental platform for studying two-dimensional (2D) physics due to its high quality, versatility and tunablity. Created by stacking graphene with other 2D materials, 2D heterostructures ...
    • Development of high frequency and wide bandwidth Johnson noise thermometry 

      Crossno, Jesse Dylan; Liu, Xiaomeng; Ohki, Thomas A.; Kim, Philip; Fong, Kin Chung (AIP Publishing, 2015)
      We develop a high frequency, wide bandwidth radiometer operating at room temperature, which augments the traditional technique of Johnson noise thermometry for nanoscale thermal transport studies. Employing low noise ...
    • Direct Observation of a Long-Lived Single-Atom Catalyst Chiseling Atomic Structures in Graphene 

      Wang, Wei Li; Santos, Elton J. G.; Jiang, Bin; Cubuk, Ekin Dogus; Ophus, Colin; Centeno, Alba; Pesquera, Amaia; Zurutuza, Amaia; Ciston, Jim; Westervelt, Robert M.; Kaxiras, Efthimios (American Chemical Society (ACS), 2014)
      Fabricating stable functional devices at the atomic scale is an ultimate goal of nanotechnology. In biological processes, such high-precision operations are accomplished by enzymes. A counterpart molecular catalyst that ...
    • Hot Carriers in Graphene 

      Song, Justin Chien Wen (2014-10-22)
      When energy relaxation between electrons and the lattice is slow, an elevated electronic temperature different from that of the lattice persists. In this regime, hot charge carriers control the energy transport in a material. ...
    • 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 ...
    • Optical Properties of Carbon Conjugated Systems 

      Yang, Yuan (2017-09-08)
      Conjugated carbon systems have played an important role historically in the theoretical study of physical phenomena and are finding many modern-day applications in electronic devices. Raman spectroscopy is a powerful tool ...
    • Single-Electron Probes of Two-Dimensional Materials 

      Levin, Andrei Joseph (2018-12-03)
      From the silicon MOSFET inversion layer to the gallium arsenide quantum well, two-dimensional electron systems (2DES) have revolutionized both physics and technology. In recent years, a novel class of atomically thin 2D ...
