Guest-Cage Atomic Interactions in a Clathrate-Based Phase-Change Material

New clathrate‐based phase‐change materials with cage‐like structures incorporating Cs and Ba guest atoms, are reported as a means of altering crystallization and amorphization behavior by controlling ‘guest‐cage’ interactions via intra‐complex guest vibrational effects. Both a high resistance to spo...

Description
Summary:New clathrate‐based phase‐change materials with cage‐like structures incorporating Cs and Ba guest atoms, are reported as a means of altering crystallization and amorphization behavior by controlling ‘guest‐cage’ interactions via intra‐complex guest vibrational effects. Both a high resistance to spontaneous crystallization, and long retention of the amorphous phase are achieved, as well as a low melting energy. This approach provides a route for achieving cage‐controlled semiconductor devices.
