Flexoelectricity in Photoconversion: Fundamentals, Materials, and Outlooks

Advanced Science, EarlyView.
Mechanical bending of a flexible cantilever induces a strain gradient in the photoactive material. The resulting flexoelectric field couples with photovoltaic and photoconductive effects, modulating charge generation, separation, and collection. A comparative analysis of oxide perovskites, halide perovskites, and two‐dimensional materials is presented,

Bridged h‐BN Nanosheets Coatings: Simultaneous Shielding Atomic‐Oxygen Irradiation and Achieving Superior Friction Performance

Advanced Science, EarlyView.
ABSTRACT To confront extreme space environments, a combination of inorganic and organic coatings can provide a pathway for offering highly durable radiation resistance and anti‐friction simultaneously. Herein, a strong interfacial 3D hydrogen‐bonding network is designed to create robust hexagonal boron nitride (h‐BN) based polymer coatings with ...

Orientation‐Engineered PtTe2 Schottky FETs: Quantum Transport Insights for Dopant‐Free Advanced Technology Nodes

Advanced Electronic Materials, EarlyView.
Monolayer PtTe2 enables dopant‐free Schottky FETs through its thickness‐dependent electronic transition. Quantum transport simulations show that crystallographic orientation strongly influences device performance, with Γ–M transport delivering higher drive current, lower leakage, and improved switching behavior.
