| Abstract: | In this paper, we assume that a phonon state in a quantum dot is a thermal coherent state. The state and energy of electron-phonon system in a quantum dot is solved by thermo field dynamics. From this, we discuss the dependence of energy and stability of the system on temperature. In addition, it is found that such system is most stable at T=0. |
