Design of 4-layered structure with single Cr-W alloy layer to achieve high and broadband photon-to-heat conversion efficiency
摘要
基于铬钨合金能带结构的研究, 得到了可表述任意铬钨合金组分光学性质的数学模型, 并将其应用于实际光热器件特性分析.根据由模型获得特定组分铬钨合金的光学性质, 设计了一个含有单层铬钨合金吸收层的四层膜结构, 显示出优异的宽光谱(300~1000 nm)光热转换性能.
Abstract
A composition dependent model based on the Cr-W alloy structure has been studied to make it possible to be put into practical application. In terms of the optical properties of the Cr-W alloy with defined composition, a simpler 4-layered structure with single Cr-W alloy absorption layer has been designed to show the merit of high photon-to-heat conversion efficiency in the broad spectral region of 300~1000 nm.
