We discuss the foundations and extend the range of applicability of the widely used Kubo-Greenwood formula (KGF) for the electronic conductivity. The conductivity is derived from the current density, and only the probability amplitude rather than the transition probability is used. It is shown that...
A simplified derivation of the Kubo-Greenwood formula 来自 Semantic Scholar 喜欢 0 阅读量: 162 作者:LL Moseley,T Lukes 摘要: A simplified derivation of the Kubo‐Greenwood‐Peierls equation is given using the quantum theory of fluctuations developed by Callen and Welton....
We present a calculation of Seebeck coefficient derived by Kubo-Greenwood formula with the density functional theory. The electronic structure calculation being the Korringa-Kohn-Rsestoker Green's function method with coherent potential approximation and local density functional method (KKR-CPA-LDA). We...

The standard linear response theory for the conductivity of 'non interacting' electrons is usually derived making the assumption that the applied gradient of the electrochemical potential is constant. However, the resulting electron distribution consists of a current carrying part and a non-current ...
Currently to find the static and dynamic conductivity the Kubo-Greenwood formula is most commonly used. It describes the electromagnetic energy absorption in the one-electron approach. In the present study, this formula is derived directly from the expression for the permittivity expression in the ...
To achieve this, we apply the continuous Kubo-Greenwood formula and extend it to include the imaginary part of the complex conductivity into the analysis. Our method is suitable for a wide range of substances, providing an opportunity to explain optical properties from ab initio calculations of ...
doi:10.1080/14786437508221628It is shown that if it is assumed that the stationary states for electrons in a weakly disordered solid are incoherent superpositions of plane-wave states the standard relaxation-time formula for the conductivity follows from the Kubo-Greenwood formula.D....
