INFLUENCE OF ELECTRON PHONON INTERACTION ON THIRD HARMONIC GENERATION IN A QUANTUM WIRE WITH PARABOLIC POTENTIAL
【摘要】 理论上计算了电子-声子相互作用对抛物量子线中三次谐波产生的影响机制,用量子力学中的密度矩阵算符理论推导了该系统中三次谐波产生的解析表达式,以典型的GaAs量子线为例进行了数值计算
【Abstract】 Theoretical predictions of polaron effects on the third harmonic generation in a rectangular quantum wire with an additional parabolic potential were presented. The formula for the third harmonic generation along the wire was derived by the density matrix method. The numerical results were presented for a typical GaAs quantum wire.
