Optical Constants of Metals in the Far Ultraviolet and their Relation to Energy Band Structure
Abstract
The real and imaginary components optical constants of the indices of refraction of silver, a silver-indium alloy, gold, gold-aluminum alloys, and aluminum have been studied in the wave length range of 304 to 1671 A. electrical conductivity as derived from the optical constants is shown to be related to interband transitions in these metals. Analysis of results for silver indium alloys indicate a breakdown of the rigid band concept. A Fermi surface which has less contact at the Brillouin zone faces and a less distorted shape is indicated for the alloy. The modified energy band structure is presented and discussed. The relation between the energy gap at Brillouin zone faces and the interband transition probability is developed and data are pre sented which demonstrate its relative importance.
