Raman Spectroscopy of Lithographically Patterned Graphene Nanoribbons
Sunmin Ryu, Janina Maultzsch, Melinda Y. Han +2
Nanometer-scale graphene objects are attracting much research interest because of newly emerging properties originating from quantum confinement effects. We present Raman spectrosc…
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…
Observation of magneto-phonon resonance of Dirac fermions in graphite
J. Yan, S. Goler, T. D. Rhone +5
Coherent coupling of Dirac fermion magneto-excitons with an optical phonon is observed in graphite as marked magnetic-field dependent splittings and anti-crossing behavior of the t…
Electron and optical phonon temperatures in electrically biased graphene
Stéphane Berciaud, Melinda Y. Han, Louis E. Brus +2
We examine the intrinsic energy dissipation steps in electrically biased graphene channels. By combining in-situ measurements of the spontaneous optical emission with a Raman spect…
Electron Transport in Disordered Graphene Nanoribbons
Melinda Y. Han, Juliana C. Brant, Philip Kim
We report an electron transport study of lithographically fabricated graphene nanoribbons of various widths and lengths at different temperatures. At the charge neutrality point, a…
Reversible Basal Plane Hydrogenation of Graphene
Sunmin Ryu, Melinda Y. Han, Janina Maultzsch +4
We report the chemical reaction of single-layer graphene with hydrogen atoms, generated in situ by electron-induced dissociation of hydrogen silsesquioxane (HSQ). Hydrogenation, fo…
