Million‐Atom Simulation of the Set Process in Phase Change Memories at the Real Device Scale

open access: yesAdvanced Electronic Materials, EarlyView.
Multimillion atom simulations reveal the subtle interplay between crystal nucleation and crystal growth from the crystal/amorphous rim in phase change memories based on the Ge2Sb2Te5 prototypical compound, at the length and time scales of the set process in the real devices.

Suppressed Thermal Conductivity in van der Waals Semiconductor SnS2 by Stacking Engineering

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Achieving low thermal conductivity is crucial for materials used for thermoelectric energy conversion. It is demonstrated that the lattice thermal conductivity of van der Waals semiconductor SnS2 can be significantly reduced by introducing 2H and 4H structures stacked along the c‐axis.
