Intrinsically ultrastrong plasmon-exciton interactions in crystallized films of carbon nanotubes
Po-Hsun Ho, Damon B. Farmer, George S. Tulevski +6
In cavity quantum electrodynamics, optical emitters that are strongly coupled to cavities give rise to polaritons with characteristics of both the emitters and the cavity excitatio…
Manipulating infrared photons using plasmons in transparent graphene superlattices
Hugen Yan, Xuesong Li, Bhupesh Chandra +6
Superlattices are artificial periodic nanostructures which can control the flow of electrons. Their operation typically relies on the periodic modulation of the electric potential…
Infrared Spectroscopy of Wafer-Scale Graphene
Hugen Yan, Fengnian Xia, Wenjuan Zhu +5
We report on spectroscopy results from the mid- to far-infrared on wafer-scale graphene, grown either epitaxially on silicon carbide, or by chemical vapor deposition. The free carr…
Chemical Doping and Electron-Hole Conduction Asymmetry in Graphene Devices
Damon B. Farmer, Roksana Golizadeh-Mojarad, Vasili Perebeinos +4
We investigate polyethylene imine and diazonium salts as stable, complementary dopants on graphene. Transport in graphene devices doped with these molecules exhibits asymmetry in e…
