Thin Fluoride Insulators for Improved 2D Transistors: From Deposition Methods to Recent Applications
physica status solidi (RRL) – Rapid Research Letters, EarlyView.2D materials hold significant promise for next‐generation electronic and optoelectronic devices, but suitable gate dielectrics are still a challenge. Fluoride insulators, offering inert, dangling‐bond‐free surfaces, have recently emerged as strong candidates. This review covers recent publications on high‐quality fluoride thin‐film deposition and their

Wafer‐Scale Self‐Limiting Epitaxy of Bernal‐Stacked Single‐Crystal Boron Nitride
Small, EarlyView.Wafer‐scale, single‐crystal Bernal‐stacked boron nitride (bBN) bilayers are grown by flow‐modulated MOCVD, where monoatomic Ni step edges on Ni(111) deterministically direct AB stacking. As an ultrathin interlayer, bBN suppresses interfacial scattering and enables robust, nonvolatile polarization switching in MoS2 channels, offering a scalable platform
