Phonon glasses—electron crystal

The filled skutterudite antimonides appear to represent excellent examples of electron-crystal, phonon-glass materials. The incoherent rattling of the loosely bound lanthanide atoms in these materials is inferred from the large values of the ADP parameters obtained in single-crystal structure refinements. This rattling lowers the thermal conductivity at room temperature to values within two to three times Km... 

Indeed, focusing on this low thermal conductivity, Slack et al. have investigated boron cluster compounds like beta boron, YB66 among others, as possible embodiments of the "electron crystal phonon glass" systems that they have proposed (Slack et al., 1971 Cahill et al., 1989).

The fact that one adamantine crystal could be produced in which the thermal conductivity was reduced to values near the theoretical minimum by an uncharged, neutral atom like xenon suggested that the phonon heat transport could be lowered in other semiconducting crystals without changing the electron concentration or their mobilities. This is the phonon glass-electron crystal, or PGEC, concept [4].
