Electronic screening in stacked graphene flakes revealed by scanning tunneling microscopy

(author unknown)



Xiaofeng Feng and Miquel Salmeron

Electronic doping and screening effects in stacked graphene flakes on Ru and Cu substrates have been observed using scanning tunneling microscopy (STM). The screening affects the apparent STM height of each flake in successive layers reflecting the density of states near the Fermi level and thus t ... [Appl. Phys.
