Probing the dark exciton states of a single quantum dot using photocurrent spectroscopy in magnetic fields

Kai Peng, Shiyao Wu, Jing Tang +8

We report on high-resolution photoluminescence (PL) and photocurrent (PC) spectroscopies of a single self-assembled InAs/GaAs quantum dot (QD) embedded in an n-i-Schottky device wi…
