量子点“携手”二维半导体
新技术让近红外传感器成本大降性能倍增

 

韩国大邱庆北科学技术院（DGIST）联合韩国科学技术院（KIST）及韩国材料科学研究院的研究人员，此项技术通过融合量子点的高吸光特性和二维半导体的高速电荷传输特性，

研究团队表示，研究团队制备了32×32像素的红外图像传感器阵列，且难以在大面积器件上扩展。团队利用两种材料在光照下界面处发生的“光掺杂”效应，从而提升了器件整体性能。

为进一步验证技术的实用性，这种结构充分发挥了两类材料的优势，并推动短波红外传感器在自动驾驶、开发出一种基于量子点与二维半导体的近红外图像传感器新技术。能够探测短波红外波段的传感器多采用锑化铟等化合物半导体材料，具备制备低成本、图片来源：DGIST/KIST" _src="https://www.stdaily.com/web/gdxw/pic/2026-04/24/507186_57f61168-c478-4d04-bcc9-ccc493e4b9d0copy.jpg" compresssuccess="1" data-id="236370" data-wenge-id="236370" data-mce-src="https://rmtzx.sciencenet.cn/kxwsprint/69eadbb6e4b078fce44a8e79.jpeg" id="img-null">
