Abstract
Some of the effects of surface and volume imperfections on the optical properties of metal films are examined. The surface can be tested by using two types of probes: plasmons and conduction electrons. The surface plasmons can be excited either by light, radiating or absorbing energy, or by electrons. The interaction of the conduction electrons with the surface manifests itself through the anomalous skin effect, which is a function of the “specularity” of the surface. Manifestations of volume defects are examined next. Granular films are investigated first by, using plasmons or simply by measuring their normal transmittance and reflectance. Some of the existing theories concerning the optical properties of such films are briefly discussed. Continuous films show various optical manifestations related to their defects. Gold films are chosen as an example and the influence of defects on free carriers and interband transitions is examined. The appearance of a new absorption band is indicated. A complete explanation of the influence of volume defects on the optical properties of metal films does not exist yet.
