Graphene: Sub‐Terahertz Frequency‐Domain Spectroscopy Reveals Single‐Grain Mobility and Scatter Influence of Large‐Area Graphene (Adv. Mater. 16/2015)
Source abstract
Abstract
On page 2635, L. Bogani and co-workers measure the electronic response of individual domains in wafer-sized chemical vapor deposition (CVD) graphene by means of contactless sub-THz interferometry. The intrinsic optical conductance of graphene is observed and the remarkable mobility is shown to be mainly limited by charged scatterers on the substrate. This sensitivity of sub-THz interferometry to contaminants can be used to easily quantify their presence and assess the quality of large graphene structures, which is essential for applications in touchscreens, as well as wearable and optoelectronic devices.
