【摘要】 量子点红外光电探测器(QDIP)凭借自身的优点,未来很有可能与碲镉汞(HgCdTe)红外探测器、量子阱红外光电探测器(QWIP)和非制冷微测辐射热计相竞争。目前,普遍采用自组织方法生长量子点,研究主要集中在:①隧道量子点红外探测器(T-QDIP);②量子阱中量子点(DWELL)红外探测器;③Si基QDIP;④Ge QDIP。本文阐述正在研究的几种QDIP,并对下一代传感器用QDIP进行预测。更多还原

【Abstract】 Quantumdot infrared photodetector(QDIP) will probably compete with HgCdTe,QWIP and uncooled microbolometer in the future because of itsself merits.Currently,QDs are grown by self-organized method.The study is focused on ①tunneling QDIP(T-QDIP);②quantum dots-in-a-well(DWELL)IP;③Si-based QDIP;④Ge QDIP.Several kinds of QDIP being developed are introduced and the QDIP used for the next-generation sensors are forecasted in this paper.更多还原
