Abstract
We study the temperature effect on the vibrational frequency and the ground state binding energy of a strong-coupling magnetopolaron in the quantum rods. The vibrational frequency and the ground state binding energy are expressed as a functions of the aspect ratio of the ellipsoid, the magnetic field cyclotron frequency,the transverse effective confinement lengths, the temperature and the electron-phonon coupling strength by using a linear combination operator and unitary transformation methods. It is found that the vibrational frequency and the ground state binding energy will increase with decreasing the transverse effective confinement lengths. They are increasing functions of the cyclotron frequency and electron-phonon coupling strength. However, they become decreasing ones of the temperature and aspect ratio.
