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…
Gate-tunable and high responsivity graphene phototransistors on undoped semiconductor substrates
Biddut K. Sarker, Isaac Childres, Edward Cazalas +2
Due to its high charge carrier mobility, broadband light absorption, and ultrafast carrier dynamics, graphene is a promising material for the development of high-performance photod…
Topological insulator based spin valve devices: evidence for spin polarized transport of spin-momentum-locked topological surface states
Jifa Tian, Isaac Childres, Helin Cao +3
Spin-momentum helical locking is one of the most important properties of the nontrivial topological surface states (TSS) in 3D topological insulators (TI). It underlies the iconic…
Planning the Future of U.S. Particle Physics (Snowmass 2013): Chapter 8: Instrumentation Frontier
M. Demarteau, R. Lipton, H. Nicholson +211
These reports present the results of the 2013 Community Summer Study of the APS Division of Particles and Fields ("Snowmass 2013") on the future program of particle physics in the…
