Unusual Force Constants Guided Distortion-Triggered Loss of Long-Range Order in Phase Change Materials

Unusual force constants originating from the local charge distribution in crystalline GeTe and Sb(2)Te(3) are observed by using the first-principles calculations. The calculated stretching force constants of the second nearest-neighbor Sb-Te and Ge-Te bonds are 0.372 and −0.085 eV/Å(2), respectively...
