在本文中，我们提出了一种集成器件，其中紫外探测器和超级电容器建立在同一垂直排列的硅纳米线（SiNW）阵列电极上。研究发现，嵌入的超级电容器具有令人印象深刻的13.6 F cm−3的电容密度，并且能够在不到100秒的时间内单次充电为探测器供电超过10小时。在整个工作期间，证明了探测器的快速稳定的紫外光响应。这种低成本高性能的设备已被证明是一种有前途的应用，其中传感器与电源无缝集成以实现其功能。
In this paper, we present an integrated device in which an UV detector and a supercapacitor are built on the same vertical-aligned silicon nanowire (SiNW) array electrode. It is found that the embedded supercapacitor is of an impressive capacitance density of 13.6 F cm−3and able to power the detector for more than 10 h with a single charge in less than 100 s. The fast and stable UV light responsivity of the detector has been demonstrated during the whole working period. This low cost high performance device has proved a type of promising applications in which a sensor is seamlessly integrated with a power source for its functions.
