Spintronics: Spin Electronics and Optoelectronics in Semiconductors

Spin electronics in semiconductors is a fascinating new field of research with high potential towards new kinds of semiconductor devices. We pick spin optoelectronics as examplary subfield and discuss from this point of view potentials, recent advances, and problems. We show spin optoelectronic devices, critically analyse spin injection and spin transport, show results concerning GaMnAs, and present data about spin dephasing in semiconductors.
