Pt Modified Sb₂Te₃ Alloy Ensuring High−Performance Phase Change Memory

Nanomaterials, 2022
Phase change memory (PCM), due to the advantages in capacity and endurance, has the opportunity to become the next generation of general−purpose memory. However, operation speed and data retention are still bottlenecks for PCM development.

Comparison of Microencapsulated Phase Change Materials Prepared at Laboratory Containing the Same Core and Different Shell Material

Applied Sciences, 2017
Microencapsulated Phase Change Materials (MPCM) are widely used in active and passive systems for thermal energy storage. To evaluate the strength of a proper shell/PCM system, comparisons were performed between laboratory-prepared MPCM samples produced ...

Composite of CNT foam and phase change material: nano pore structure and the packing of phase change material

Journal of Aeronautical Materials, 2019
Thermal energy is a very promising and widely existing energy source. However, the current heat storage method of phase change material not only has a long energy conversion time but also has low heat storage efficiency.

Active analog tuning of the phase of light in the visible regime by bismuth-based metamaterials

Nanophotonics, 2020
The active and analog tuning of the phase of light by metamaterials is needed to boost the switching performance of photonic devices. However, demonstrations of this type of tuning in the pivotal visible spectral region are still scarce.

Resonant multilevel optical switching with phase change material GST

Nanophotonics, 2022
We demonstrate a multilevel optical memristive switch based on a silicon Fabry–Perot resonator. The resonator is constructed by a pair of waveguide Bragg gratings at the ends of a multimode interferometer (MMI) covered with sub-micrometer-size Ge2Sb2Te5 (
