First-principle calculations and experimental investigation on the infrared emissivity property of Mg-doped ZnO
Source abstract
Abstract
Abstract The electronic properties and infrared emissivity of Zn 1-x Mg x O (x = 0, 0.0625, 0.125) were systematically investigated by using the first-principle calculation s based on density functional theory (DFT). The Zn 1-x Mg x O (x = 0, 0.0625, 0.125) powders were prepared by sol-gel method and their infrared emissivity in the wavelength of 8–14 μm was characterized. The results indicate that the infrared emissivity increases with the increase in Mg concentration, which is attributed to the reduction in conductivity and in the real part of dielectric function. Furthermore, the variation in conductivity and dielectric function has been well studied, and a reasonable method to calculate infrared emissivity of semiconductors has been established. It is expected that this method can be used for designing materials with different infrared emissivity and also applied for effectively guiding the experimental investigation.
