Dynamic nuclear spin polarization in self-assembled quantum dots under zero magnetic field

Ryosuke Matsusaki, Reina Kaji, Sohta Yamamoto +2

We studied the zero-field dynamic nuclear spin polarization in a single In${}_{0.75}$Al${}_{0.25}$As/Al${}_{0.3}$Ga${}_{0.7}$As quantum dot. Even without any external magnetic field, the p…
