In this paper, the band structure, optical absorption spectra and quantum efficiency of graphene nanoribbons photodetector at both modulated and constant external transverse electric field have been investigated. Our calculations show that applying the electric field would modify the band gap, remove the states degeneracy, alter the sub-band spacing, cause the changes in the optical absorption spectra, and affect the quantum efficiency. We show that the strength and the period of the electric field have important effects on the adsorption coefficient and quantum efficiency peaks.
Keywords: Quantum Efficiency, Graphene Nanoribbon, Transverse Electric Field
