| Abstract: | In light of the semiclassical (Thomas-Fermi) approximate method, the thermodynamic properties of the charged fermion system in homogeneous weak electrical field are studied. After deriving the relationship of heat capacity and chemical potential of charged fermion system changed with external electrical field, then the analytic formula of the chemical potential and heat capacity of the charged fermion system in the high and low temperature approximation condition, and the influence of the homogeneous weak electrical field on the chemical potential and heat capacity are analyzed. |

| Keywords: | charged particle system heat capacity chemical potential homogeneous weak electric field |
