Multiple exciton generation can increase the detectivity in photodetectors but has limited effect in infrared detectors. Now, a strategy for kinetically pumped avalanche multiplication has been demonstrated in colloidal quantum dot-based infrared photodetectors, achieving an 85-fold multiplication gain and ultrahigh detectivity of 1.4 × 1014 Jones.

具有超高探测率的量子点光电探测器的雪崩倍增


多激子的产生可以提高光电探测器的探测能力，但在红外探测器中效果有限。现在，一种基于胶体量子点的红外光电探测器已经证明了一种动力学泵浦雪崩倍增策略，实现了 85 倍的乘法增益和 1.4 × 1014 Jones 的超高探测率。
