Abstract
According to one embodiment, at least a portion of the phase change material including a first crystalline phase is converted to one of a second crystalline phase and an amorphous phase. The second crystalline phase transitions to the amorphous phase more easily than the first crystalline phase. For example, the first crystalline phase may be a hexagonal closed packed structure, and the first crystalline phase may be a face centered cubic structure.
