Enhanced Optical Modulation Depth of Terahertz Waves by Self‐Assembled Monolayer of Plasmonic Gold Nanoparticles

Abstract

Ultra-large-area self-assembled mono­layers of gold nanoparticles are coated on the intrinsic silicon to boost the generation of electron–hole pairs upon laser illumination. As a result, larger optical modulation depth of terahertz wave can be obtained by the monolayer coated silicon in comparison with the bare silicon.
