Advanced Science, EarlyView.Multilayered AgBiP2Se6 has been systematically characterized to be a quasi‐direct semiconductor using theoretical calculations and optical experiments. It possesses an indirect bandgap of 1.46 eV and a direct gap of 1.535 eV for simultaneously absorbing the NIR to visible‐light photons. In combination with a p‐type Ga0.5In0.5Se, a high efficiency p‐Ga0.

Local structural changes associated with relaxor behavior in Sn-doped BaTiO_{3}
Physical Review ResearchPolar nanoregions (PNRs) play an important role in relaxor ferroelectrics. Despite decades of research, structural understanding of their formation is lacking. In this study, we investigate how PNRs form by using Ti K-edge x-ray absorption fine structure

Advanced Science, EarlyView.By exploiting the strong nonlinear optical response and controllable molecular ordering of ferroelectric nematic liquid crystals (FNLCs), these materials can serve as tunable sources of polarization‐entangled photons. Adjusting the sample geometry or applying an external electric field enables continuous control of the entanglement degree, advancing ...

Advanced Science, EarlyView.This study demonstrates a TiN/HfO2/ITO memristor exhibiting field‐induced bimodal volatile switching behavior originating from ion bombardment during sputtering. The dipole‐driven, polarity‐dependent states produce multilevel output responses that expand the reservoir's output dimensionality and enhance encoding diversity.
