Phase Shift between Exciton and Free Carrier Polarization in Semiconductor Quantum Wells

Not Accessible

Your library or personal account may give you access

Abstract

Two-color pulse-shaping technique is used to probe the relative phase between exciton and free carrier polarizations in four-wave mixing. It appears that the virtual excitation of excitons at free carrier energies is an important contribution.
