Aging in Phase Change Materials: Getting Insight from Simulation

Simulation of Phase Change Materials Using Cellular Automata

The most promising media for rewritable applications are the phase change materials [1]. For the modelling of the phase transition processes in phase change materials was used the minimum switching unit called “commuton” [2]. A commuton is a minimum cluster of atoms that supports a reversible change from OFF to ON state under the influence of an external applied energy pulse. It was developed a...

An Algorithm based on Predicting the Interface in Phase Change Materials

Phase change materials are substances that absorb and release thermal energy during the process of melting and freezing. This characteristic makes phase change material (PCM)  a favourite choice to integrate it in buildings. Stephan problem including melting and solidification in PMC materials is an practical problem in many engineering processes. The position of the moving boundary, its veloci...

Thermal Transport in Phase Change Memory Materials

Phase change memory uses brief pulses of electrical current to induce phase transitions in chalcogenide material regions with dimensions near or even far below 50 nm. The strongly differing electrical conductivities of the crystalline and amorphous phases allow data storage at densities in excess of terabits per square inch. Nanoscale conduction heat transfer governs the figures of merit in the...
