Real-Space Plasmon Imaging Reveals Modified Electronic Structure of Gold at the Monolayer Limit
Andrei Bylinkin, Philippe Roelli, Naveen Shetty +8
Atomically thin materials exhibit electronic and optical properties distinct from their three-dimensional counterparts. For metals, particularly gold, monolayer studies remain larg…
Nature of photoexcited states in ZnO-embedded graphene quantum dots
Ivan Shtepliuk, Rositsa Yakimova
The combination of wide-band gap semiconductors like zinc oxide (ZnO) and graphene quantum dots (GQDs) is a promising strategy to tune optoelectronic properties of GQDs and to deve…
Scalable fabrication of edge contacts to 2D materials
Naveen Shetty, Hans He, Richa Mitra +9
We present a fabrication method for reliably and reproducibly forming electrical contacts to 2D materials, based on the tri-layer resist system. We demonstrate the applicability of…
Highly efficient UV detection in a metal-semiconductor-metal detector with epigraphene
Hans He, Naveen Shetty, Sergey Kubatkin +7
We show that epitaxial graphene on silicon carbide (epigraphene) grown at high temperatures (T > 1850 °C) readily acts as material for implementing solar-blind ultraviolet (UV) det…
Electron-phonon coupling of epigraphene at millikelvin temperatures
Bayan Karimi, Hans He, Yu-Cheng Chang +7
We investigate the basic charge and heat transport properties of charge neutral epigraphene at sub-kelvin temperatures, demonstrating nearly logarithmic dependence of electrical co…
Ambipolar charge transport in quasi-free-standing monolayer graphene on SiC obtained by gold intercalation
Kyung Ho Kim, Hans He, Claudia Struzzi +6
We present a study of quasi-free-standing monolayer graphene obtained by intercalation of Au atoms at the interface between the carbon buffer layer (Bu-L) and the silicon-terminate…
