Noise Analysis of Monolayer Graphene Nanopores [PDF]

open access: yesInternational Journal of Molecular Sciences, 2018
Graphene-based nanopore devices have shown tantalizing potential in single molecule detection for their monoatomic membrane thickness which is roughly equal to the gap between nucleobases. However, high noise level hampers applications of graphene nanopore sensors, especially at low frequencies. In this article, we report on a study of the contribution

Surface Defect Healing in Annealing from Nanoporous Carbons to Nanoporous Graphenes

open access: yesPhysical Chemistry Chemical Physics, 2023
Nanoporous graphene (NPG) materials have the pronounced electrochemical stability of the seamless graphene structures developed over the 3D space. We revisited the Raman spectra of nanoporous carbons (NPCs) synthesized using θ-/γ-Al2O3 templates and NPGs converted from NPCs by annealing at 1800 ºC to identify the type and density of defects.
