Effect of oxygen plasma etching on graphene studied with Raman spectroscopy and electronic transport
Isaac Childres, Luis A. Jauregui, Jifa Tian +1
We report a study of graphene and graphene field effect devices after exposure to a series of short pulses of oxygen plasma. We present data from Raman spectroscopy, back-gated fie…
Control and Characterization of Individual Grains and Grain Boundaries in Graphene Grown by Chemical Vapor Deposition
Qingkai Yu, Luis A. Jauregui, Wei Wu +14
The strong interest in graphene has motivated the scalable production of high quality graphene and graphene devices. Since large-scale graphene films synthesized to date are typica…
Measurements of Dihadron Correlations Relative to the Event Plane in Au+Au Collisions at GeV
H. Agakishiev, M. M. Aggarwal, Z. Ahammed +366
Dihadron azimuthal correlations containing a high transverse momentum () trigger particle are sensitive to the properties of the nuclear medium created at RHIC through the str…
Effect of electron-beam irradiation on graphene field effect devices
Isaac Childres, Luis A. Jauregui, Mike Foxe +4
Electron beam exposure is a commonly used tool for fabricating and imaging graphene-based devices. Here we present a study of the effects of electron-beam irradiation on the electr…
Scaling properties at freeze-out in relativistic heavy ion collisions
STAR Collaboration, M. M. Aggarwal
Identified charged pion, kaon, and proton spectra are used to explore the system size dependence of bulk freeze-out properties in Cu+Cu collisions at =200 and 62.4 G…
Measurement of the Bottom contribution to non-photonic electron production in collisions at =200 GeV
STAR Collaboration, M. M. Aggarwal
The contribution of meson decays to non-photonic electrons, which are mainly produced by the semi-leptonic decays of heavy flavor mesons, in collisions at 20…
