Optical Control of Chiral Charge Pumping in a Topological Weyl Semimetal
M. Mehdi Jadidi, Mehdi Kargarian, Martin Mittendorff +8
Solids with topologically robust electronic states exhibit unusual electronic and optical transport properties that do not exist in other materials. A particularly interesting exam…
Tunable Ultrafast Thermal Relaxation in Graphene Measured by Continuous-Wave Photomixing
M. Mehdi Jadidi, Ryan J. Suess, Cheng Tan +9
Hot electron effects in graphene are significant because of graphene's small electronic heat capacity and weak electron-phonon coupling, yet the dynamics and cooling mechanisms of…
Hybrid Metal-Graphene Plasmons for Tunable Terahertz Technology
Mohammad M. Jadidi, Andrei B. Sushkov, Rachael L. Myers-Ward +6
Among its many outstanding properties, graphene supports terahertz surface plasma waves -- sub-wavelength charge density oscillations connected with electromagnetic fields that are…
Sensitive Room-Temperature Terahertz Detection via Photothermoelectric Effect in Graphene
Xinghan Cai, Andrei B. Sushkov, Ryan J. Suess +10
Terahertz (THz) radiation has uses from security to medicine; however, sensitive room-temperature detection of THz is notoriously difficult. The hot-electron photothermoelectric ef…
