Hole-electron competition with fast and slow gratings in Bi(12)SiO(20) crystals.
Two samples of nominally pure Bi(12)SiO(20) show distinct behavior in experiments of diffraction efficiency kinetics, and two-beam coupling. The results can be understood by the presence of fast and slow gratings due to electrons and holes.
