Synthesis of Amorphous‐Crystalline Mixture Boron Nitride for Balanced Resistive Switching Operation

open access: yesSmall, EarlyView.
An amorphous–crystalline mixture BN (acm‐BN) is synthesized through low‐pressure chemical vapor deposition, achieving balanced resistive switching with low SET voltage and stable RESET. High‐resolution transmission electron microscopy reveals that BN films are fully amorphous at 930 °C, a mixed amorphous–crystalline phase is achieved at 990 °C.

Wafer‐Scale Self‐Limiting Epitaxy of Bernal‐Stacked Single‐Crystal Boron Nitride

open access: yesSmall, 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
