Optical tracing of multiple charges in single-electron devices

摘要:

在低温下表现出窄光学跃迁的单分子可以用作局部电场传感器。基于第一性原理,我们推导了芳香族有机染料分子的单电荷灵敏度。通过数值模拟,我们证明,通过使用目前可用的技术,它是可能的光学检测充电事件在一个粒状网络的灵敏度优于$10^{-5}e/\sqrt{\textrm{Hz}}$和跟踪多个电子的位置,同时,与纳米空间分辨率。我们的研究结果为电子和自旋电子纳米器件的微创光学检测以及构建在单光子和单电子水平上发挥作用的混合光电接口铺平了道路。

英文摘要:

Single molecules that exhibit narrow optical transitions at cryogenic temperatures can be used as local electric-field sensors. We derive the single charge sensitivity of aromatic organic dye molecules, based on first principles. Through numerical modeling, we demonstrate that by using currently available technologies it is possible to optically detect charging events in a granular network with a sensitivity better than $10^{-5}e/\sqrt{\textrm{Hz}}$ and track positions of multiple electrons, simultaneously, with nanometer spatial resolution. Our results pave the way for minimally-invasive optical inspection of electronic and spintronic nanodevices and building hybrid optoelectronic interfaces that function at both single-photon and single-electron levels.
