Area of Science:

  • Materials Science
  • Condensed Matter Physics
  • Nanotechnology

Background:

  • Heteroatom doping engineers graphene nanoribbons (GNRs) electronic properties.
  • Precise oxygen atom integration into GNRs and its effects are largely unexplored.

Purpose of the Study:

  • To precisely embed oxygen atoms into GNR lattices.
  • To synthesize and characterize oxygen-doped GNRs (O-GNRs).
  • To investigate the impact of oxygen doping on GNR electronic properties.

Main Methods:

  • In situ formation of pyrans for oxygen incorporation.
  • Synthesis of O-doped chevron-GNR and O-doped chiral (2,1)-GNR.
  • Scanning tunneling microscopy (STM) and noncontact atomic force microscopy (nc-AFM).
  • Density functional theory (DFT) calculations.

Main Results:

  • Successfully synthesized two types of O-GNRs.
  • Both O-GNRs exhibit direct bandgap semiconducting behavior.
  • Oxygen dopants have a minor effect on chevron-GNR bandgap but a significant effect on chiral (2,1)-GNR bandgap.
  • O-doping in chiral (2,1)-GNR leads to unexpected band edge transitions and Fermi surface shifts.

Conclusions:

  • Precise oxygen doping is achievable in GNRs.
  • The electronic properties of O-GNRs are sensitive to dopant concentration and GNR structure.
  • O-doping offers a pathway to tune the electronic properties of GNRs for potential applications.
