摘要

Using laser pulses of duration comparable to semiconductor relaxation anddephasing times, the coherent phenomena common to two-level systems have been demonstrated in II-VI and III-V semiconductors. These light-matter interactions are characterized by electrons and holes in their initially excited states and/or a macroscopic polarization that persists after the excitation. semiconductors, lasers, macroscopic polarization.
