强增强的声等离子体激元在光激发的非平衡电子空穴等离子体中的大块半导体被证明是导致超短(\ensuremath{\sim}10 fs)的退相时间和非常高的载流子-载流子散射率。
Strong enhancement of acoustic plasmons in optically excited nonequilibrium electron-hole plasmas in bulk semiconductors is shown to cause ultrashort (\ensuremath{\sim}10 fs) dephasing times and very high carrier-carrier scattering rates.
