High-Performance All-Optical Terahertz Modulator Based on Graphene/TiO(2)/Si Trilayer Heterojunctions

In this paper, we demonstrate a trilayer hybrid terahertz (THz) modulator made by combining a p-type silicon (p-Si) substrate, TiO(2) interlayer, and single-layer graphene. The interface between Si and TiO(2) introduced a built-in electric field, which drove the photoelectrons from Si to TiO(2), and...
