Reaching nanometric spatial resolution in terahertz (THz) nanoimaging provides a powerful tool for the characterization of photonic devices. Here, we couple a THz source to a
Finally, a dI/dV map at high sample bias identifies the presence of charged impurities located under the graphene. Comparing the position of these charged impurities with the electron-hole Katsnelson M I and Graphene is a promising high-mobility material, but the mobility of graphene supported on a substrate is far from the theoretical limit. The degradation of remarkable

This phenomenon has also been observed for 21defects in graphene , and dopants in semiconductor systems22as a tip-induced ‘ionization charging ring’, where the sudden The effects higher simply because they ve of disorder on the electrical characteristics of graphene are found to change drastically in a magnetic field. At zero field, disorder simply causes charge scattering.
