  • Visible light detector with high-photoresponse based on TiO/MoSheterojunction and preparation thereof
    Patent number: 11961934
    Abstract: In the field of photoelectric devices, a visible light detector is provided with high-photoresponse based on a TiO2/MoS2 heterojunction and a preparation method thereof. The detector, based on a back-gated field-effect transistor based on MoS2, includes a MoS2 channel, a TiO2 modification layer, a SiO2 dielectric layer, Au source/drain electrodes and a Si gate electrode, The TiO2 modification layer is modified on the surface of the MoS2 channel. By employing micromechanical exfoliation and site-specific transfer of electrodes, the method is intended to prepare a detector by constructing a back-gated few-layer field-effect transistor based on MoS2, depositing Ti on the channel surface, and natural oxidation.

  • METHOD FOR SCALING VEHICLE CRASH DUMMY MODEL
    Publication number: 20240104262
    Abstract: A method for scaling a vehicle crash dummy model, includes: obtaining a height ratio, a girth ratio, and a mass ratio of each part of a body shape of a target population to a reference population; calculating part scaling ratios of the target population to the reference population in a height direction and each direction in a girth plane according to the height ratio, the girth ratio, and the mass ratio; scaling simulation models of each part of a dummy simulation model of the reference population according to each scaling ratio; and assembling scaled models of each part, to obtain a dummy simulation model of the target population. This embodiment improves a shape simulation degree for a real human body of a dummy.
