Résumé:
In semiconductors optically enhanced polarization of nuclei is known to be primarily due to photoexcited electrons. We show that holes play a role in this process via the spin-dependent recombination of the carriers. Our results are obtained in n-type InP where spin-dependent recombination leads to the inversion of the nuclear field direction due to the donor spins cooling under optical excitation.
