Abstract
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.
