Area of Science:

  • Materials Science
  • Condensed Matter Physics
  • Nanotechnology

Background:

  • Graphene quantum dots (GQDs) show potential in electronics, optoelectronics, and bioelectronics.
  • Fabricating widely tunable GQDs with precise control has been a significant challenge.

Purpose of the Study:

  • To report the fabrication of atomically precise GQDs with tunable electronic properties.
  • To explore the relationship between GQD structure and its fundamental bandgap.

Main Methods:

  • Fabrication of GQDs via edge fusion of armchair graphene nanoribbons (AGNRs).
  • Utilizing scanning tunneling microscopy/spectroscopy (STM/STS) for characterization.
  • Employing extensive computational simulations for analysis.

Main Results:

  • Atomically precise GQDs were successfully fabricated from N=7 AGNR edge fusion.
  • GQDs exhibited atomically sharp interfaces and low-lying interface states.
  • The fundamental bandgap was tuned over one order of magnitude by controlling segment length.

Conclusions:

  • The developed fabrication method enables wide tunability of GQD bandgaps.
  • These tunable GQDs are promising for developing novel electronic and optoelectronic devices.
