Storage of Photoexcited Electron—Hole Pairs in an AlAs/GaAs Heterostructure Created by Electron Transfer in Real and κ Spaces
彭进, 胡冰
Abstract
The storage of photoexcited electron-hole pairs is experimentally carried out and theoretically realized by transferring electrons in both real and κ spaces through resonant Γ-X in and AlAs/GaAs heterostructure,This is proven by the peculiar capacitance jump and hysteresis in the measured capacitance-voltage curves.Our structure may be used as a photonic memory cell with a long storage time and a fast retrieval of photons as well.
