Ultrasensitive Indium Phosphide Nanomembrane Wearable Gas Sensors

Energy & environment materials, Год журнала: 2024, Номер 7(6)

Опубликована: Май 15, 2024

Air quality is deteriorating due to continuing urbanization and industrialization. In particular, nitrogen dioxide (NO 2 ) a biologically environmentally hazardous byproduct from fuel combustion that ubiquitous in urban life. To address this issue, we report high‐performance flexible indium phosphide nanomembrane NO sensor for real‐time air monitoring. An ultralow limit of detection ~200 ppt fast response have been achieved with device by optimizing the film thickness doping concentration during epitaxy. By varying thickness, dynamic range values parts per trillion (ppt) million (ppm) level also demonstrated under low bias voltage at room temperature without additional light activation. Flexibility measurements show an adequately stable after repeated bending. On‐site testing residential kitchen shows gas stove emission could exceed Time Weighted Average limit, i.e., 200 ppb, highlighting significance Critically, element cost estimated <0.1 US$ miniatured size, nanoscale ease fabrication. With these superior performance characteristics, cost, real‐world applicability, our sensors offer promising solution variety monitoring applications.
