Template-directed growth unlocks metastable stacking symmetry and tailorable crystal phases in multicomponent alloys, enabling improved efficiency and long-term stability in proton exchange membrane water electrolysis.

Vacancy Engineering of Solution Processed CuI Semiconductor: Tuning the Electrical Properties of Inorganic P-Channel Thin Film Transistors Recently, copper iodide (CuI) has been considered as a promising inorganic p-type semiconductor material. Although significant progress using CuI has been made in materials and device applications for solar cells and thin-film transistors (TFTs), little consideration has been given to the vacancy formation mechanisms and their effect on the device performance.
