Electronic properties of bottom-up fabricated graphene nanoribbons

• Applicant: Professorin Dr. Petra Tegeder
• Subject Area: Experimental Condensed Matter Physics
• Term: from 2014 to 2017
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 257739120

The goal of the project is to utilize a thermally-activated on-surface synthesis to generate various atomically precise sub-nanometer wide graphene nanoribbons (GNRs) with different widths, edge shapes and degrees of doping to gain insight into the influence of these parameters on the electronic properties of GNRs. This aims at controlling the size of band gaps and position of valence and conduction bands with respect to the Fermi level of a metal electrode. The bottom-up synthesis of the GNRs using particular precursor molecules will be followed by vibrational high resolution electron energy loss spectroscopy (HREELS) and scanning tunneling microscopy. Their electronic properties are analyzed by time- and angle-resolved two-photon photoemission spectroscopy and electronic HREELS.
