Detection of spin polarization utilizing singlet and triplet states in a single-lead quantum dot
Tomohiro Otsuka, Yuuki Sugihara, Jun Yoneda +2
We propose and demonstrate a new method to probe local spin polarization in semiconductor micro devices at low and zero magnetic fields. By connecting a single-lead quantum dot to…
