Article Synopsis
- Semiconducting epigraphene (SEG) exhibits a band gap of 0.6 eV and high mobility, outperforming silicon and existing 2D semiconductors.
- Attempts to create viable semiconducting graphene in the past have largely failed, but SEG represents a breakthrough by using a quasi-equilibrium annealing method on silicon carbide substrates.
- The properties of SEG, such as its robustness and compatibility with standard fabrication techniques, make it a promising material for advanced nanoelectronics applications.
High-resolution scanning electrochemical cell microscopy (SECCM), synchronously visualizing the topography and electrochemical activity, could be used to directly correlate the structure and activity of materials nanoscopically. However, its topographical measurement is largely restricted by the size and stability of the meniscus droplet formed at the end of the nanopipette. In this paper, we report a scheme that could reliably gain several tens nanometer resolution (≥65 nm) of SECCM using homemade ∼50 nm inner diameter probes.
