HOPPING CONDUCTIVITY OF NANOSTRUCTURED CHAIN: REAL-SPACE RENORMALIZATION GROUP APPROACH
纳米结构链的hopping电导实空间重正化群方法

In terms of Miller-Abrahams' theory, a real-space renormalization group approach is developed to calculate the hopping conductivity of one-dimensional nanostructured chain.It is found that the kinds and the sizes,as well as the interface structures and lattice distortion,of nano-grains have a notable effect on the hopping conductivity of nanostructured systems.
