Zinc Oxide Nanowire Photodetector

Zinc Oxide Nanowire Photodetector
This scanning electron microscope image shows a zinc oxide (ZnO) nanowire photodetector device grown by photolithography. Nanowires geometry and structure make them both sensitive to light and efficient low-noise signaling devices, so they are ideally suited for applications involving light—such as detection, imaging, information storage, and intrachip optical communications. In addition, different types of nanowires can be combined to create devices sensitive to different wavelengths of light. Zinc oxide's (ZnO) electrical, optoelectronic, and photochemical properties have led to its use in solar cells, transparent electrodes, and blue/UV light-emitting devices.
