| Abstract: | In this paper, using the linear combination operator and unitary transformation method, we study the mean number of phonons in the cloud around the electron in polaron for the weak electron- LO- phonon coupling cases of the quantum rod with parabolic confinement potentials. It is shown that the mean number of phonons is dependent on the electron- LO - phonon coupling constant and aspect ratio. |
