The invention relates to a photo-thermal detector, a system and a preparation method, and mainly relates to the technical field of photo-thermal detection. According to the invention, a plurality of conical holes are formed in the metal layer; under the action of a tip effect, a large amount of charges can be gathered at the tip of the conical cavity; the molybdenum disulfide layer has excellent carrier mobility; meanwhile, molybdenum disulfide laminated metal particles are coupled; the electron transfer speed in the molybdenum disulfide layer is accelerated; the metal particles are arranged at the bottom of the molybdenum disulfide; molybdenum disulfide has ultrathin physical properties. The contact area of the molybdenum disulfide layer and the metal unit is further increased; the chargetransfer rate is further increased, the measurement result is more accurate when the photothermal detector detects the light intensity according to the relation between photothermoelectricity, and due to the fact that the charge transfer rate of the photothermal detector is greatly increased, the photothermal measurement sensitivity is high.
Description
technical field [0001] The invention relates to the technical field of photothermal detection, and mainly relates to a photothermal detector, a system and a preparation method. Background technique [0002] The photothermal effect refers to the electrical characteristics of the material change caused by the temperature change. The photothermal detector is used to obtain the light intensity of the light to be measured by detecting the heat generated by the light through the relationship between light and heat. [0003] In the prior art, the measurement of light intensity is calculated by the formula, I=Nhv / At, wherein, I represents the light intensity in the optics, v represents the frequency of light, A is the area of the irradiation area, and N is the time interval t The total number of photons that hit A. [0004] However, the above calculation method needs to measure the total number of photons N, and due to the influence of the existing technology, the accuracy of mea...
