Liquid anomalies and Fragility of Supercooled Antimony
Flavio Giuliani, Francesco Guidarelli Mattioli, Yuhan Chen +5
Phase-change materials (PCMs) based on group IV, V, and VI elements, such as Ge, Sb, and Te, exhibit distinctive liquid-state features, including thermodynamic anomalies and unusua…
Microscopic model of the operation of the Single-chalcogenide X-point Memory
P. Fantini, A. Ghetti, E. Varesi +8
Ovonic threshold switching is the key process for several applications of chalcogenide alloys including phase change memories and selector elements in cross-points arrays. Very rec…
Viscosity, breakdown of Stokes-Einstein relation and dynamical heterogeneity in supercooled liquid GeSbTe from simulations with a neural network potential
Simone Marcorini, Rocco Pomodoro, Omar Abou El Kheir +1
Phase change materials are exploited in non-volatile electronic memories and photonic devices that rely on a fast and reversible transformation between the amorphous and crystallin…
From Continuous to First-Order-Like: Amorphous-to-Amorphous Transition in Phase-Change Materials
Tomoki Fujita, Yoshio Kono, Yuhan Chen +13
Polymorphism is ubiquitous in crystalline solids. Amorphous solids, such as glassy water and silicon, may undergo amorphous-to-amorphous transitions (AATs). The nature of AATs rema…
Simulation of the crystallization kinetics of GeSbTe nanoconfined in superlattice geometries for phase change memories
Debdipto Acharya, Omar Abou El Kheir, Simone Marcorini +1
Phase change materials are the most promising candidates for the realization of artificial synapsis for neuromorphic computing. Different resistance levels corresponding to analogi…
Million-atom simulation of the set process in phase change memories at the real device scale
Omar Abou El Kheir, Marco Bernasconi
Phase change materials are exploited in several enabling technologies such as storage class memories, neuromorphic devices and memories embedded in microcontrollers. A key function…
