Detection of spin polarization utilizing singlet and triplet states in a single-lead quantum dot
Detection of spin polarization utilizing singlet and triplet states in a single-lead quantum dot
We propose and demonstrate a new method to probe local spin polarization in semiconductor microdevices at low and zero magnetic fields. By connecting a single-lead quantum dot to a semiconductor microdevice and monitoring electron tunneling into singlet and triplet states in the dot, we can detect the local spin polarization …
