VO2: A Phase Change Material for Micromechanics

Proceedings, 2017
Micro- and nano-mechanical systems may take advantage from using materials having multiple functional characteristics. VO2 is a compound characterised by a solid state phase transition (SSPT) just above room temperature, consisting in a concurrent metal ...

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 (

Miniature Multilevel Optical Memristive Switch Using Phase Change Material [PDF]

ACS Photonics, 2019
The optical memristive switches are electrically activated optical switches that can memorize the current state. They can be used as optical latching switches in which the switching state is changed only by applying an electrical Write/Erase pulse and ...

The contribution and FIP bias of three types of materials inside ICMEs associated with different flare intensities [PDF]

arXiv, 2023
The studies on the origination and generation mechanisms of ICME materials are crucial for understanding the connection between CMEs and flares. The materials inside ICMEs can be classified into three types, coming from corona directly (corona-materials), heated by magnetic reconnection in corona (heated-corona-materials), and generated by ...

Measurement method for T-h properties of phase change material

Journal of Asian Architecture and Building Engineering, 2023
In this study, a simple and inexpensive T-h property measurement method was proposed for measuring the temperature and specific enthalpy of a flat plate phase change material (PCM) by cooling and heating it under adiabatic conditions on one side and ...
