The decay of a surface plasmon, a collective electron oscillation at the surface of a metal, can generate hot charge carriers that may be transferred to an adjacent semiconductor. This plasmon-induced charge transfer process can be used to enhance ph

The mid-infrared spectra of many polar materials are dominated by highly reflective reststrahlen bands that occur between the transverse and longitudinal optical phonons. Within the reststrahlen bands, light can couple with optical phonons to support
