Book excerpt: A transmission electron microscopy study involving direct and replicating techniques is directed to a definition of the microstructure of radio frequency-sputtered, thin lead-dielectric cermet films. Once defined, this microstructure is used to obtain theoretical film refractive indices. The Maxwell Garnett theory provides a basis for the theoretical results. Measurements of film transmission and reflectivity are used to obtain rough experimental values for film refractive indices by the Tekucheva method. More exact values are obtained via ellipsometry. The rough Tekucheva values are used to determine the range over which computer calculations interpreting the ellipsometric results must be made. This technique yields accurate values for the film refractive indices. The films are radio frequency-sputtered from lead glass targets with varying amounts of lead attached to their faces. Three different targets are used, resulting in three sets of films, each containing a different percentage of lead. The lead content of the films is measured by microprobe analysis as well as visual inspection of micrographs. The lower content lead films are seen to consist of tiny balls of lead embedded in the dielectric, as are the intermediate lead content films; but the higher lead content films form metallic with the predictions of the Maxwell Garnett theory; but the higher lead content films, whose structure fails to conform to the Maxwell Garnett configuration, have indices whose values diverge from the Maxwell Garnett predictions. It is thus shown that the theory of Maxwell Garnett is valid for thin cermet films whose structure consists of tiny metal balls embedded in a dielectric medium.

This book was released on 2021-08-23 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents an overview of both the theory and experimental methods required to realize high efficiency solar absorber devices. It begins with a historical description of the study of spectrally selective solar absorber materials and structures based on optical principles and methods developed over the past few decades. The optical properties of metals and dielectric materials are addressed to provide the background necessary to achieve high performance of the solar absorber devices as applied in the solar energy field. In the following sections, different types of materials and structures, together with the relevant experimental methods, are discussed for practical construction and fabrication of the solar absorber devices, aiming to maximally harvest the solar energy while at the same time effectively suppressing the heat-emission loss. The optical principles and methods used to evaluate the performance of solar absorber devices with broad applications in different physical conditions are presented. The book is suitable for graduate students in applied physics, and provides a valuable reference for researchers working actively in the field of solar energy.
