摘要
在方形的量的第三泛音的产生上的电子声子相互作用的影响很好被调查。第一泛音、第三泛音的产生系数被使用 compact-density-matrix 途径和反复的方法获得，并且数字结果为 GaAs 方形的量被介绍很好。结果证明第三泛音的产生系数显然在考虑电子声子相互作用的影响以后被提高。
The influence of electron-phonon interactions on third-harmonic generation in a square quantum well is investigated. The first- and third-harmonic generation coefficient is obtained by using compact-density-matrix approach and iterative method, and the numerical results are presented for a GaAs square quantum well. The results show that the third-harmonic generation coefficient is obviously enhanced after considering the influence of electron-phonon interactions.
