Efficient Electron Spin Detection with Positively Charged Quantum Dots

Not Accessible

Your library or personal account may give you access

Abstract

Using polarization sensitive time-resolved photoluminescence upconversion experiments, we demonstrate that positively charged quantum dots act as a highly efficient detector for spin polarized electrons in semiconductor heterostructures.
