Adsorption of metals on Si9C15 monolayer for optoelectronic applications

Two dimensional materials have a bright application prospect in the field of optoelectronic devices. As a newly discovered polymorph of the third-generation semiconductor SiC, Si9C15's single-layer structure may have excellent optoelectronic properties, which has significant practical implications for the study of two-dimensional Si9C15. By employing the first-principles density functional theory, a comprehensive analysis is performed on the electronic, magnetic, work function, and optical absorption properties of a monolayer structure Si9C15 with metal atom adsorption. The adsorption of different metal semiconductors has changed their properties. The adsorption of metal atoms not only reduces the work function of Si9C15, but also enhances its light absorption ability in the visible light region. This finding highlights the potential for enhancing the optical properties of the Si9C15 system through metal adsorption. The utilization of spherical metal nanoparticles on Si9C15 nanosheets to induce local surface plasmon resonance is an exciting development. The results indicate that the Si9C15 system adsorbed with metal atoms could be employed in the manufacturing of spin electronic device, field emission devices, and solar photovoltaic devices. This suggests that the improved optical properties of the Si9C15 system could have significant implications for advancing these technologies.
