Abstract

The problem of heat conduction in layered La2-x SrxCuO4 superconductor has been investigated in a new frame work of in-plane and cross-plane concepts with the help of modified Callaway model of thermal conductivity based on relaxation time approximation. Using the many body quantum dynamical theory of the expressions for thermal conductivity in context of in-plane and cross plane have been obtained and results are found in excellent agreement with experimental observations for layered La2-x SrxCuO4 cuprate superconductors. The theory explores the possibility of device fabrication cold in one direction and hot in the other.
