| 中文摘要 | The Lee, Low and Pines' variational method is employed to study the interaction of electron-confined phonons within a rectangular quantum wire under an additional parabolic potential. Detailed mathematical derivation is carried out to obtain some formulae for the polaron self-energy, the electron effective mass along the wire and the ground state energy. Using the idea of Fourier decomposition of wavefunctions, numerical calculations are performed for a typical GaAs quantum wire within the mesoscopic size. Our present results show that the effect of phonon confinement always reduces the magnitude of the electron-phonon interaction and the associated physical quantities whereas the additional parabolic potential tends to enhance both the electron-phonon interaction and the ground state energy. Comparing with previous calculations, our results also reveal the trends of those interesting physical quantities. |
