ABSTRACT:
An ultraviolet detector (UV-detector) including a substrate, a first electrode, and a second electrode is provided. The UV-detector substrate comprises an active region for absorbing ultraviolet light and generating charges. The first electrode is electrically connected to the active region and has a plurality of first tips. Additionally, the second electrode is electrically connected to the active region and has a plurality of second tips. The second electrode is electrically insulated from the first electrode. The first and second tips facilitate the conduction of the charge generated by the photoelectric effect, and the sensitivity of the UV-detector is thus enhanced.
