Extended Data Fig. 6: Raman spectrum of monolayer epitaxial graphene on SiC.

From: Light-field control of real and virtual charge carriers

Extended Data Fig. 6

The coupling to the SiC induces a strain-induced blue-shift of 64 cm–1 to the 2D-peak compared to freestanding graphene, while it consists of one peak only (~48 cm–1 FWHM) as expected for monolayer graphene36. The occurrence of a D-peak indicates defects emerging primarily from domain boundaries37.
