Orbital Geometry‐Governed Response of Pressure‐Tunable Quantum Defects in hBN
Advanced Functional Materials, EarlyView.Defects in hBN act as ultrasensitive quantum manometers when the energy of the intradefect optical transitions is modified by lattice compression. The orbital geometry of the electron wave functions governs how electron hopping and Coulomb interactions react uniquely to the reduction of the van der Waals gap and in‐plane compression, leading to robust ...

Titanium Suboxides Responsible for Electronic Anomaly Near Room Temperature in the Ti3C2Tx MXene
Advanced Functional Materials, EarlyView.Our multi‐technique study reveals that the near‐room‐temperature anomaly in Ti3C2Tx MXene is linked to titanium suboxide nanodomains, including Ti3O5, embedded within the MXene host. Their temperature‐driven transformation provides an alternative explanation to solvent‐ and swelling‐based models and offers new insight into the thermally activated ...

Valence-band structure of InN from x-ray photoemission spectroscopy
, 2005 The valence-band structure of clean, high-quality, single-crystalline wurtzite InN thin films prepared with atomic hydrogen is investigated using x-ray photoemission spectroscopy. The In 4 d 5 ∕ 2 semicore level due to the In-N bond is found to lie 16.

Advanced Functional Materials, EarlyView.This work presents a dual‐function interface engineering strategy using PEACl to suppress the formation of the non‐perovskite δ‐FAPbI3 phase at the critical SnO2 buried interface. This approach enables the direct crystallization of the photoactive α‐phase, yielding highly efficient and stable rigid (25.6%) and flexible perovskite solar cells with ...
