To address the demand for rapid detection of toxic gases (C2H2, C2H4, CH4 and H2) released during lithium-ion batteries (LIBs) thermal runaway, this study uses first-principles calculations to investigate adsorption behavior. First, two modification methods are considered, namely surface doping of pure ZnO (TM-ZnO) and defect doping containing Zn vacancies (TMD-ZnO).

We propose a metasurface framework for enhancing terahertz (THz) third-harmonic generation (THG) using quasi-bound states in the continuum (quasi-BICs) at critical coupling. The THz nonlinear metasurface comprises a silicon rod dimer structure integrated with monolayer graphene.

A graphene-dielectric metasurface driven by quasi-bound states in the continuum (BICs) is proposed for enhanced dual-mode absorption in the terahertz (THz) regime. The graphene-dielectric metasurface is composed of a periodic array of cross-shaped slabs and monolayer graphene.
