In recent years, the energy consumption of computing systems has increased and a large fraction of this energy is consumed in main memory. Towards this, researchers have proposed use of non-volatile memory, such as phase change memory (PCM), which has low read latency and power; and nearly zero leakage power. However, the write latency and power of PCM are very high and this, along with limited...

This study shows results of the experimental investigation of regularly structured Composite Latent Heat Storages. Common solid-liquid Phase Change Materials used as latent heat storages have a low thermal conductivity, which leads to high temperature differences inside large PCM volumes. This drawback is compensated by the combination with specially designed frame-structures made of aluminum t...

In this work, we numerically demonstrate an all-optical tunable Fano resonance in a fishnet metamaterial(MM) based on a metal/phase-change material(PCM)/metal multilayer. We show that the displacement of the elliptical nanoholes from their centers can split the single Fano resonance (FR) into a double FR, exhibiting higher quality factors. The tri-layer fishnet MMs with broken symmetry accompli...

Structural defects and their dynamics play an important role in controlling the behavior of phase-change materials (PCM) used in low-power nonvolatile memory devices. However, not much is known about the influence of disorder on the electronic properties of crystalline PCM prior to a structural phase-change. Here, we show that the application of voltage pulses to single-crystalline GeTe nanowir...

Plasmonic sensing is an established technology for real-time biomedical diagnostics and air-quality monitoring. While intensity wavelength tracking are the most commonly used interrogation methods Surface Plasmon Resonance (SPR), several works indicate potential superiority of phase in detection sensitivity. Here, we theoretically numerically establish link between ultra-high sensitivities SPR ...

A solar photovoltaic (PV) system produces electrical energy from energy. This green, sustainable has low conversion efficiency due to the rise in PV temperature throughout day. In order keep of panels close ambient, this study examines usage hydrated salt (HS36) as a Phase Change Material (PCM) for cooling. The primary goal experimental is cool panel by introducing PCM behind (PV-PCM), thus inc...
