Abstract: The potential for spin-based information processing in spintronic devices has spurred significant research on spin coherence in semiconductors. We review some recent advances in the physics of semiconductor spin coherence, focusing on phenomena in both bulk and heterostructure systems. Coherent spin ensembles can be generated and manipulated optical, electrical, and magnetic interactions. Optical measurement techniques enable both temporal and spatial resolution of spin dynamics, allowing observation of electrical control and generation of spin polarization, including the recent discovery of the spin Hall effect. Spin dynamics are also studied for spins confined in quantum dots. [ABSTRACT FROM AUTHOR]
