概要
- 論文の詳細を見る
Static conductivity is investigated for a three-dimensional disordered lattice model proposed by Lloyd by using the diagrammatical expansion technique of the Green function method. The ensemble-averaged transport time τ_<tr> is shown to go to zero not slower than (h^^/V^2/Γ^3) when (V/Γ) tends to zero, where V is the typical transfer energy and Γ the fluctuation breadth of the random site energies while the life time τ_l remains to be of the order of (h^^//Γ). This reduction arises from the vertex corrections to the ensemble-averaged two-particle Green function.
