The tribovoltaic effect is regarded as a newly discovered semiconductor effect for mechanical‐to‐electrical energy conversion. However, tribovoltaic nanogenerators (TVNGs) are widely limited by low output power and poor wear resistance for device integration and application. Here, this work invents a TVNG using a ball‐on‐disk structure composed of gallium nitride (GaN) and steel ball. It exhibits...
Direct neutron detection based on semiconductor crystals holds promise to transform current neutron detector technologies and further boosts their widespread applications. It is, however, long impeded by the dearth of suitable materials in the form of sizeable bulk crystals. Here, high‐quality centimeter‐sized LiInP2Se6 single crystals are developed using the Bridgman method and their structure and...
