On-chip Fabrication of High Performance Nanostructured ZnO UV Detectors
Developing rationally controlled bottom-up device fabrication processes is essential for the achievement of high performance optimal devices. We report a controlled, seedless and site-selective hydrothermal technique to fabricate high-performance nanostructured ZnO UV-detectors directly on-chip. We demonstrate that by controlling the nanowire growth process, via tuning the experimental paramete...

متن کاملPersistent Photoconductivity Studies in Nanostructured ZnO UV Sensors
The phenomenon of persistent photoconductivity is elusive and has not been addressed to an extent to attract attention both in micro and nanoscale devices due to unavailability of clear material systems and device configurations capable of providing comprehensive information. In this work, we have employed a nanostructured (nanowire diameter 30-65 nm and 5 μm in length) ZnO-based metal-semicond...
متن کاملFabrication and characterization of ZnO nanowires based UV photodiodes
A heterojunction of n-type zinc oxide (ZnO) nanowires and p-type silicon has been successfully constructed to demonstrate ultraviolet (UV) photodiodes. The prototype device consists of naturally doped n-type ZnO nanowires grown on top of a (1 0 0) p-silicon substrate by the bottom-up growth process. The diameter of the nanowires is in the range of 70–120 nm, and the length is controlled by the ...
متن کاملHigh-Performance Integrated ZnO Nanowire UV Sensors on Rigid and Flexible Substrates
Due to the large surface area-to-volume ratio and high quality crystal structure, single nanowire (NW)-based UV sensors exhibit very high on/off ratios between photoresponse current and dark current. Practical applications require a large-scale and low-cost integration, compatibility to fl exible electronics, as well as reasonably high photoresponse current that can be detected without high-pre...
