水对微波场损耗机理的研究

水分子是一种强极性分子，在外加交变电场作用下，将产生很强的取向极化，与此同时还将产生位移极化，因此介质内部及表面上便出现宏观的电荷和电流分布。极化电流的产生必定会带来相应的热损耗，从该角度出发，研究水对微波场的损耗。以自由水为研究对象，建立了相关的理论模型，并加以公式推导。

First-principles study of the electronic structures and optical properties of C-F-Be doped wurtzite ZnO

正The electronic structure and optical properties of pure,C-doped,C-F codoped and C-F-Be clusterdoped ZnO with a wurtzite structure were calculated by using the density functional theory with the plane-wave ultrasoft pseudopotentials method.The results indicate that p-type ZnO can be obtained by C incorporation,and the energy level of C_O above the valence band maximum is 0.36 eV.The ionization energy of the complex Zn_(16)O_(14)CF and Zn_(15)BeO_(14)CF can be reduced to 0.23 and 0.21 eV,individually.These results suggest that the defect complex of Zn_(15)BeO_(14)CF is a better candidate for p-type ZnO.To make the optical properties clear,we investigated the imaginary part of the complex dielectric function of undoped and C-F-Be doped ZnO.We found that there is strong absorption in the energy region lower than 2.7 eV for the C-F-Be doped system compared to pure ZnO.     

First-principles study of the electronic structures and optical properties of C--F--Be doped wurtzite ZnO

The electronic structure and optical properties of pure, C-doped, C-F codoped and C-F-Be cluster-doped ZnO with wurtzite structure were calculated by density functional theory with the plane-wave ultrasoft pseudopotentials method. The results indicate that p-type ZnO can be obtained by C incorporation, and the energy level of CO above valence band maximum is 0.36 eV. The ionization energy of the complex Zn16O14CF and Zn15BeO14CF can be reduced to 0.23 and 0.21 eV, individually. These results suggest that the defect complex of Zn15BeO14CF is a better candidate for p-type ZnO. To make optical properties clear, we investigated the imaginary part of the complex dielectric function of undoped and C-F-Be doped ZnO. We found that there are strong absorption in the energy region less than 2.7 eV for C-F-Be doped system comparing to pure ZnO.
