Photothermal therapy is an emerging method of cancer treatment in which tumors are ablated by heating agents using near-infrared light (700–1000 nm). A semiconductor with a bandgap between 0.3–0.7 eV would, therefore, efficiently emit near-infrared light. The new “magic” material graphene has a bandgap of zero, which is advantageous with regard to designing a new material with a suitable bandgap for the emission of near-infrared light. In our investigations, using the first-principles density functional theory calculation method, we aimed to and successfully designed graphene-based materials with a direct bandgap of 0.68 eV. They have the potential to be optimal and efficient near-infrared light sources due to their narrow yet fitting bandgap. The present results open up a new avenue for the application of graphene-based materials to assist in photothermal therapy.

We survey expressions of the effective modal volume, Veff, commonly used in the literature for nanoscale photonic and plasmonic cavities. We apply different expressions of Veff to several canonical cavities designed for nanoscale near-infrared light sources, including metallo-dielectric and coaxial geometries. We develop a metric for quantifying the robustness of different Veff expressions to the different cavities and materials studied. We conclude that no single expression for Veff is universally applicable. Several expressions yield nearly identical results for cavities with well-confined photonic-type modes. For cavities with poor confinement and a low quality factor, however, expressions using the proper normalization method need to be implemented to adequately describe the diverging behavior of their effective modal volume. The results serve as a practical guideline for mode analysis of nanoscale optical cavities, which show promise for future sensing, communication, and computing platforms.
