electron-phonon coupling
解釋
電子聲子耦合-
The results indicate that in niobate glasses, as the concentration of nb2o5 increases, the covalence becomes strong, the symmetry becomes low and the electron - phonon coupling becomes strong, thus the lifetimes become short, the nonradiative transition processes and the temperature - quenching become strong and the value of crystal field parameter b20 becomes small

We conduct a theoretical study on the properties of a bound polaron in a quantum well under an electric field using linear combination operator and unitary transformation methods, which are valid in the whole range of electron - lo phonon coupling
摘要採用線性組合算符及幺正變換方法研究了電場對量子阱弱耦合束縛極化子的性質的影響。 -
By magnetoelectric coupling, the application of an electric field or ferroelectric polarization can change one or more of the parameters governing the ma gnetic behavior of the system. correspondingly, being possible magnetostrictive effect or electron - phonon interaction, the fluctuation of spin ordering may lead to a dielectric anomaly and ferroelectric relaxation
通過磁電耦合，鐵電有序或外電場可導致自旋的再分佈而改變系統的磁性性質，同樣由於自旋有序的漲落通過磁致伸縮或可能的電-聲子作用可導致鐵電弛豫或介電異常。 -
Abstract : we conduct a theoretical study on the properties of a bound polaron in a quantum well under an electric field using linear combination operator and unitary transformation methods, which are valid in the whole range of electron - lo phonon coupling. the changing relations between the ground - state energy of the bound polaron in the quantum well and the coulomb bound potential, the electric field strength, and the well width are derived. the numerical results show that the ground - state energy increases with the increase of the electric field strength and the coulomb bound potential and decreases as the well width increases
文摘:採用線性組合算符及幺正變換方法研究了電場對量子阱弱耦合束縛極化子的性質的影響.推導出量子阱中束縛極化子的基態能量和庫侖束縛勢、電場和阱寬的變化關系.數值計算結果表明，基態能量因電場和庫侖束縛勢的不同而不同，隨電場和庫侖束縛勢的增大而增大，隨阱寬的增大而迅速減小 -
Because there exists the different strength of coupling between the electron and phonon, there have some different ways, such as the perturbation theory, variation theory, green function theory and the feynman " s path integral approach. they can be appropriately used in different area
