Raman spectra and electron-phonon coupling in disordered graphene with gate-tunable doping
Isaac Childres, Luis A. Jauregui, Yong P. Chen
We report a Raman spectroscopy study of graphene field-effect transistors (GFET) with a controlled amount of defects introduced in graphene by exposure to electron-beam irradiation…
Electrical and thermal conductivities of reduced graphene oxide/polystyrene composites
Wonjun Park, Jiuning Hu, Luis A. Jauregui +2
The author reports an experimental study of electrical and thermal transport in reduced graphene oxide (RGO)/polystyrene (PS) composites. The electrical conductivity () of RGO/P…
Gate Tunable Relativistic Mass and Berrys phase in Topological Insulator Nanoribbon Field Effect Devices
Luis A. Jauregui, Michael T. Pettes, Leonid P. Rokhinson +2
Transport due to spin-helical massless Dirac fermion surface state is of paramount importance to realize various new physical phenomena in topological insulators, ranging from quan…
