Graphene Twistronics: Tuning the Absorption Spectrum and Achieving Metamaterial Properties

Graphene twistronics using multilayer graphene is presented in such a way that it provides metamaterial effect. This manuscript also analyzes the prediction of behavior machine learning. The effect achieved by twisting layers. new concept for changing electrical and optical properties bilayer applying small angle twist between twists 5°, 10°, 15° are analyzed proposed design. Tuning absorption spectrum to angles graphene. Results form absorption, conductivity, permeability, permittivity, impedance different angles. twisted layers demonstrate negative permittivity similar metamaterials. These refraction provide flexibility transparency, which can be applied photovoltaic applications. Machine-learning-based regression models used reduce simulation time resources. results show model reliably estimate intermediate wavelength values with an R2 0.9999.
