Electrical control of single-photon emission in highly-charged individual colloidal quantum dots
Sergii Morozov, Evangelina L. Pensa, Ali Hossain Khan +6
Electron transfer to an individual quantum dot promotes the formation of charged excitons with enhanced recombination pathways and reduced lifetimes. Excitons with only one or two…

Objective-free excitation of quantum emitters with a laser-written micro parabolic mirror
Sergii Morozov, Stefano Vezzoli, Ali Hossain Khan +2
The efficient excitation of quantum sources such as quantum dots or single molecules requires high NA optics which is often a challenge in cryogenics, or in ultrafast optics. Here…
