Abstract
The influences of the temperature on the effective mass of the weak-coupling polaron in an asymmetry quantum dot are studied by using the Tokuda's improved linear-combination operator and the Lee-Low-Pines (LLP) variational method. The results indicate that the effective mass m∗ of the weak-coupling polaron is only related to the temperature parameterγ and the electron-phonon coupling strength α, but it is independent of the confinement strengthω1 (ω2) of the quantum dot.
