Phase change materials (PCMs) use latent heat of phase to store heat, which has the advantages high energy storage density and low-temperature fluctuation. And it can be applied many fields such as building envelope Heating Ventilation Air Conditioning (HVAC) system. The PCM is a kind material with great potential, positively impacts conservation indoor environment improvement. In this paper, r...

Phase-change material (PCMs) store data using the contrast (electrical or optical) between two phases: a conductive crystalline phase and weakly amorphous phase. Most PCMs have distorted octahedral structure. The comes mainly from electronic In PCMs, spontaneous symmetry breaking mechanism, Peierls distortion, transforms metallic structure into lower-density semiconducting simple tight-binding ...
