Electron-phonon coupling effect on the optical absorption of gated β-borophene

This study addresses the effect of electron-phonon coupling (EPC) on the electro-optical properties of gated β 12 -borophene. The focus is on how EPC influences the orbital hybridization of boron atoms, particularly within the Bari ic-Labbe-Friedel-Su-Schrieffer-Heeger framework, and considers the r...

Description
Summary:This study addresses the effect of electron-phonon coupling (EPC) on the electro-optical properties of gated β 12 -borophene. The focus is on how EPC influences the orbital hybridization of boron atoms, particularly within the Bari ic-Labbe-Friedel-Su-Schrieffer-Heeger framework, and considers the role of gate electrodes in this process. The results reveal a redshift in the optical spectrum only when there is positive feedback from one electrode on EPC. In other configurations, except for the y -direction, a blueshift spectrum is observed. The study emphasizes the importance of tuning these spectral shifts for maximizing the performance of solar cells in converting sunlight into usable energy. This study addresses the effect of electron-phonon coupling (EPC) on the electro-optical properties of gated β 12 -borophene.
