Highly durable and energy‐efficient probabilistic bits based on h‐BN/SnS2 interface for integer factorization

open access: yesInfoMat, Volume 7, Issue 7, July 2025.
This study introduces a novel probabilistic bit (p‐bit) device utilizing advanced materials, hexagonal boron nitride (h‐BN) and tin disulfide (SnS2), to enhance durability and energy efficiency in computational applications. By leveraging the stochastic behavior of electron trapping and detrapping at the h‐BN/SnS2 interface, the device achieves ...

Phase‐Change Heterostructures Based on Antimony

open access: yesphysica status solidi (RRL) – Rapid Research Letters, Volume 19, Issue 7, July 2025.
Switching cycle of a phase‐change superlattice heterostructure consisting of alternating nanolayers of antimony and TiTe2 is simulated using ab initio and machine‐learned molecular dynamics. It is shown that it is possible to switch the Sb layer without destroying the confinement layer.

Partial Melting and Structural Disorder in Models of Irradiated Amorphous Ge2Sb2Te5

open access: yesphysica status solidi (RRL) – Rapid Research Letters, Volume 19, Issue 7, July 2025.
The evolution of the potential energy landscape of glassy Ge2Sb2Te5$\left(\text{Ge}\right)_{2} \left(\text{Sb}\right)_{2} \left(\text{Te}\right)_{5}$ during irradiation indicates the partial melting of the model structure. This view provides a thermodynamic insight into the fast recovery of the amorphous network after irradiation. The chemical disorder
