基于二维半导体的图像传感器OACSTPCD

Image sensors,as crucial devices for capturing visual information,convert perceived light signals into electrical outputs.Cur-rently,the manufacturing technology for image sensors based on complementary metal-oxide-semiconductor is quite mature.However,there is still a demand for miniaturized and multifunctional image sensors in certain specific application scenarios.Facing this challenge,image sensors based on two-dimensional(2D)semiconductors,with their rich material systems and excellent photoelectric properties,demonstrate potential in miniaturization and high integration,offering new opportunities for the development of the image sensor field.This paper first discusses the bandgap characteristics of 2D semiconductors and their corresponding spectral response ranges,showcasing single-pixel imaging technology based on 2D semiconductors.It then describes how the in-plane anisotropic properties of atomic arrange-ments in 2D semiconductors are utilized to successfully construct polarization-sensitive image sensors.Finally,it explores how the ongo-ing maturation of large-area growth technologies for 2D semiconductor materials can further facilitate the construction of image sensor arrays based on 2D semiconductors.
