Layered 2D/3D perovskite bilayer heterostructures have the potential to boost the performance and durability of many types of electronic and photonic devices, but maintaining this performance depends on the stability of the cell’s 2D interlayer. In this study, researchers optimized time-resolved, spontaneous thin-film deposition of 2D perovskites using a mixed solvent approach to produce phase pure, stable thin films with high crystallinity.

Pinpointing Magnetic Mysteries and Mechanisms in a Layered Perovskite
The strontium ruthenate family has a perovskite-like structure that can assemble into different configurations, offering an ideal way to study how the physics change as the material goes from 3D to 2D. In this study, researchers revealed how electrons with different spins behave in distinct layers of a three-layer magnetic material. The results deepen the field’s understanding of how magnetism emerges in layered materials, an important concept for future magnetic technologies and quantum electronic devices. Read more »
Researchers Identify Viral Swiss Army Knife, Clarifying How Replication Occurs
Viruses are ingenious, infectious agents, capable of replicating inside the living cells of a host organism. Enterovirus, a common viral pathogen, is responsible for a range of diseases from mild colds to severe conditions, including viral meningitis, myocarditis, and paralysis. A new study sheds light on how enteroviruses use structured RNA elements and multifunctional proteins to coordinate viral replication efficiently using minimal genetic material. Read more »
