High-resolution spatial mapping of the temperature distribution of a Joule self-heated graphene nanoribbon
Young-Jun Yu, Melinda Y. Han, Stephane Berciaud +5
We investigate the temperature distributions of Joule self-heated graphene nanoribbons (GNRs) with a spatial resolution finer than 100 nm by scanning thermal microscopy (SThM). The…
Visualizing Individual Nitrogen Dopants in Monolayer Graphene
Liuyan Zhao, Rui He, Kwang Taeg Rim +15
In monolayer graphene, substitutional doping during growth can be used to alter its electronic properties. We used scanning tunneling microscopy (STM), Raman spectroscopy, x-ray sp…
Multiband Transport in Bilayer Graphene at High Carrier Densities
Dmitri K. Efetov, Patrick Maher, Simas Glinskis +1
We report a multiband transport study of bilayer graphene at high carrier densities. Employing a poly(ethylene)oxide-CsClO solid polymer electrolyte gate we demonstrate the fil…
Bolometric and non-bolometric radio frequency detection in a metallic single-walled carbon nanotube
Daniel F. Santavicca, Joel D. Chudow, Daniel E. Prober +2
We characterize radio frequency detection in a high-quality metallic single-walled carbon nanotube. At a bath temperature of 77 K, only bolometric (thermal) detection is seen. At a…
Making ARPES Measurements on Corrugated Monolayer Crystals: Suspended Exfoliated Single-Crystal Graphene
Kevin R. Knox, Andrea Locatelli, Mehmet B. Yilmaz +6
Free-standing exfoliated monolayer graphene is an ultra-thin flexible membrane, which exhibits out of plane deformation or corrugation. In this paper, a technique is described to m…
Graphene field-effect transistors based on boron nitride gate dielectrics
I. Meric, C. R. Dean, A. F. Young +3
Graphene field-effect transistors are fabricated utilizing single-crystal hexagonal boron nitride (h-BN), an insulating isomorph of graphene, as the gate dielectric. The devices ex…
