Abstract

Halide Perovskites The illustration depicts charge carriers preserving their quantum phase coherence as they traverse grain boundaries in halide perovskite thin films, revealing a striking grain-size-independent behavior. Subsequent investigations uncover that phase coherence is not limited by microstructural features but dictated largely by crystal structure (or strain). More details can be found in the Research Article by Jose L. Mendoza-Cortes, Johannes Pollanen, Richard R. Lunt, William J. Gannon, and co-workers (DOI: 10.1002/admi.202500567).
