Abstract
Identifying the major factors that govern the structural and electronic quality of large area graphene is of great importance for its technological implementation. By using contactless sub-THz interferometry, we could measure the electronic response of individual domains in wafer-sized CVD graphene. Using multilayer transparent structures we could observe the intrinsic optical conductance of graphene, as predicted by theoretical models.
