Abstract

The invention discloses a high-sensitivity ultraviolet light detector. An ultraviolet-light absorption-type organic film is taken as a photoelectric absorption layer so as to absorb ultraviolet light and grapheme with high mobility is taken as a current channel transmission carrier. Photoelectric reaction time can be greatly shortened and photoelectric sensitivity of a device is increased. Simultaneously, the grapheme and the organic film are flexible materials so that a feasible scheme is provided for flexible integration of the device.

Description

technical field [0001] The invention relates to the technical field of semiconductors, and more specifically, to a high-sensitivity ultraviolet light detector and a manufacturing method thereof. Background technique [0002] The ultraviolet light band is generally distributed in the range of 200nm to 400nm, and can usually be divided into three parts, namely: UVA320~340nm, UVB290nm~320nm and UVC200~240nm. Usually, UVC in the sun will be absorbed by the ozone layer, UVB will cause strong photodamage to the epidermis, and UVA will pass through the epidermis and enter the dermis, causing the epidermis to age and darken. [0003] The ultraviolet light detector is a kind of detector, which can convert the ultraviolet light signal into a measurable electrical signal through the photovoltaic mode and the photoconductive mode by using the photosensitive element. [0004] In civil and military applications, the detection of ultraviolet light has been widely used, and ultraviolet lig...
