摘要：

Dynamic nuclear self-polarization (DYNASP) is a phenomenon observed in III-V semiconductors. When electrons of the valence band of a semiconductor are optically excited to the conduction band, a relaxation process of the conduction electrons induces a large nuclear polarization to suddenly occur below a critical temperature. This mechanism is useful for nuclear magnetic moment measurements of unstable nuclei implanted in semiconductors. (C) 2013 Elsevier B.V. All rights reserved.
