Abstract

We report here the first observation of enhanced photoyields at the surface plasma resonance in silver using molecular adsorbates. Monolayer and sub-monolayer coverings of polar and nonpolar molecules were found to be sufficient to reduce the work function below the energy of the surface plasmon. Different yields were obtained on continuous than on quasi-continuous metal films. Enhancements by factors up to 10² were obtained. Cesium was used as an adsorbate for comparison.
