摘要：

The phonon glass and electron crystal (PGEC) approach has been introduced as a method to develop new, improved thermoelectric materials. The purpose of the present work is to demonstrate the serious limitation to the PGEC approach. It is shown that zT approx. 4 cannot be obtained mainly by reducing the lattice thermal conductivity and combining it with the best electrical properties of currently known materials.
