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…
The performance limits of epigraphene Hall sensors
Hans He, Naveen Shetty, Thilo Bauch +5
Epitaxial graphene on silicon carbide, or epigraphene, provides an excellent platform for Hall sensing devices in terms of both high electrical quality and scalability. However, th…
Chemical sensing with atomically-thin metals templated by a two-dimensional insulator
Kyung Ho Kim, Hans He, Marius Rodner +8
Boosting the sensitivity of solid-state gas sensors by incorporating nanostructured materials as the active sensing element can be complicated by interfacial effects. Interfaces at…
Size confinement effect in graphene grown on 6H-SiC (0001) substrate
V. M. Mikoushkin, V. V. Shnitov, A. A. Lebedev +5
We have observed the energy structure in the density of occupied states of graphene grown on n-type 6H-SiC (0001). The structure revealed with photoelectron spectroscopy is describ…
Non-contact method for measurement of the microwave conductivity of graphene
L Hao, J Gallop, S Goniszewski +4
We report a non-contact method for conductivity and sheet resistance measurements of graphene samples using a high Q microwave dielectric resonator perturbation technique, with the…
