Abstract
Spin transport between two semiconductors of widely different band gaps is time resolved by two-color pump-probe optical spectroscopy. Electron spin coherence is created in a GaAs substrate and subsequently appears in an adjacent ZnSe epilayer at temperatures ranging from 5 to 300 K. The data show that spin information can be protected by transport to regions of low spin decoherence, and regional boundaries used to control the resulting spin coherent phase.
