In recent years

with the development of several experimental techniques

for example

molecular beam epitaxy and metal-organic chemical-vapour deposition

there has been of considerable interest in lowdimensional semiconductor structures such as quantum dots

quantum wells and quantum wires.There has been more and more interest in quantum dots due to novel physical property and extensive application prospects. In the past over ten years

many people studied the properties of a bound magnetopolaron in a parabolic quantum dot extensively by using many kinds of methods both theoretically and experimentally.In this paper

the influence of the temperature on the properties of weak-coupling bound magetopolaron in a parabolic(quantum) dot is studied.The vibration frequency

the ground state energy and the mean number of phonons of the weak-coupling bound magnetopolaron in a parabolic quantum dot are derived by using the linear(combination) operator and the unitary transformation method.The relations between the vibration frequency

the ground state energy and the mean number of phonons of the weak-coupling bound magnetopolaron with the temperature are discussed.Numerical calculations

for the CdTe crystal as an example

are performed and the results indicate that the vibration frequency of weak-coupling bound magnetopolaron in a quantum dot will(increase) with increasing the temperature

the mean number of phonons of weak-coupling bound magnetopolaron will increase with increasing the temperature and will increase with decreasing the vibration frequency of magnetopolaron.The ground state energy of the weak-coupling bound magnetopolaron will increase strongly with increasing the confinement strength of the quantum dot

and at the same position(same value of ω

0

)

the higher temperature

the higher is the value of ground state energy.This is because crystal will be polarized more easily

LO-phonons will become manifold with the increasing of temperature.In this case

the interaction of electron and more LO-phonons makes the ground state energy and the mean number of phonons of the weak-coupling bound magnetopolarn increase in a quantum dot.
