Sub-Terahertz Frequency-Domain Spectroscopy Reveals Single-Grain Mobility and Scatter Influence of Large-Area Graphene

The response of individual domains in wafer-sized chemical vapor deposition graphene is measured by contactless sub-terahertz interferometry, observing the intrinsic optical conductance and reaching very high mobility values. It is shown that charged scatterers limit the mobility, validating previous theoretical predictions, and sub-terahertz quality assessment is demonstrated, as necessary for large-scale applications in touchscreens, as well as wearable and optoelectronic devices. © 2015 WILEY-VCH Verlag GmbH & Co.
