Determination of the energy gaps in metals by an optical method
Mash E.D., Motulevich G.P., Shubin A.A.
A method is proposed for separating the interband-conduction bands, and is based on the use of the analytic properties of the complex dielectric constant connected with the interband transitions. The method makes it possible to determine the number of interband conduction bands and to obtain the position of the maxima of the individual bands, and thereby determine the energy gaps in metals. The method is used to analyze the experimental results for vanadium.
