Impact of Sapphire Substrate Reconstruction on the Structural, Electronic, and Photonic Properties of MoS2

Small, EarlyView.
High‐temperature reconstruction of c‐plane sapphire during MOCVD growth of MoS2 fundamentally alters the optical and electronic properties of MoS2 epilayer by introducing step‐edge driven interfacial charge transfer. Raman, PL, and KPFM reveal non‐uniform doping and strain in as‐grown films, whereas transferred layers show uniform optical and ...

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

Hole Polaronic Confinement in (111) Yttria‐Stabilised Zirconia

Small, EarlyView.
Ultrathin epitaxial YSZ(111) films unexpectedly develop p‐type mixed conduction and amplified electromechanical coupling under oxidizing conditions. Combined transport measurements and first‐principles modeling reveal that nanoscale confinement and ordered dopant–vacancy complexes stabilize localized O 2p hole polarons at the surface. A canonical ionic
