Phase change material thermoelectric generator

open access: yesHeat and Mass Transfer, 2023
This paper aims to study and analyze a new Peltier cell layout using a PCM in biphasic mode, with the liquid phase encapsulating the p-n junctions and the solid one playing the role of heat sink. The selected PCM is an organic compound that operates within a temperature range corresponding to the melting process.

Fractal and Fractional Derivative Modelling of Material Phase Change

open access: yesFractal and Fractional, 2020
An iterative approach is taken to develop a fractal topology that can describe the material structure of phase changing materials. Transfer functions and frequency response functions based on fractional calculus are used to describe this topology and ...

Progressive amorphization of GeSbTe phase-change material under electron beam irradiation

open access: yes, 2019
Fast and reversible phase transitions in chalcogenide phase-change materials (PCMs), in particular, Ge-Sb-Te compounds, are not only of fundamental interests, but also make PCMs based random access memory (PRAM) a leading candidate for non-volatile ...

Chaotic behavior in Casimir oscillators: A case study for phase change materials [PDF]

open access: yes, 2017
Casimir forces between material surfaces at close proximity of less than 200 nm can lead to increased chaotic behavior of actuating devices depending on the strength of the Casimir interaction. We investigate these phenomena for phase change materials in
