Mapping nanoscale carrier confinement in polycrystalline graphene by terahertz spectroscopy

Abstract Terahertz time-domain spectroscopy (THz-TDS) can be used to map spatial variations in electrical properties such as sheet conductivity, carrier density, and carrier mobility in graphene. Here, we consider wafer-scale graphene grown on germanium by chemical vapor deposition with non-uniformi...
