Correlation between THz AC and micro-four-point-probe DC conductivity mapping of graphene sheets
Paper i proceeding, 2012
We present quantitative correlation mapping of the sheet conductance of large areas of graphene. Terahertz time-domain spectroscopy (THz-TDS) maps the nanoscale conductance averaged over the beam spot size whereas micro four-point probe (M4PP) maps the micro-scale conductance.
