Self-assembled organic monolayers on epitaxial graphene with enhanced structural and thermal stability

Abstract

Scanning tunnelling microscopy and X-ray reflectivity are used to characterize adlayers of perylenetetracarboxylic diimide (PTCDI) deposited on epitaxial graphene (EG) on SiC(0001). PTCDI adopts a herringbone structural phase on EG/SiC that can accommodate sub-5 nm voids with molecularly defined boundaries and isolated molecular vacancies at room temperature. The PTCDI monolayer remains intact up to substrate temperatures of ∼260 °C, thus demonstrating enhanced thermal stability compared to previously studied perylene derivatives on EG/SiC.
