| Abstract: | The low-temperature and high-density expansions of statistical thermodynamic quantities both for two-and three-dimensional Fermi gases with boundary modifications were obtained by generalizing the standard approach of quantum statistical thermodynamics.Based on the results,several factors which influence the boundary effects on quantum-dot systems were discussed.Boundary effects on practical low-temperature quantum-dot systems were calculated briefly.The results may provide theoretical hasis for researches of thermodynamical properties in quantum-dot systems. |
