Abstract
The authors report the fabrication of a 3-D ZnO-nanowire/MOSFET smart photo sensor using through silicon via technology. It was found that the MOSFET, prepared by hot-wire chemical vapor deposition, exhibits standard saturation and pinch-off characteristics. The dynamic response of the 3-D ZnO-nanowire/MOSFET smart photo sensor was stable and reproducible with an ON-OFF current contrast ratio larger than one order of magnitude. As we turned OFF the ultraviolet illumination, it was found that the decay time was smaller than 1 s for the 3-D ZnO-nanowire/MOSFET smart photo sensor, which was significantly shorter than that observed from the conventional ZnO nanowire photo sensor.
