【Abstract】 In this paper, we theoretically proposed the method using discrete electronic states in the calculation of Fermi-level of metal nanoparticles in the insulator, and also calculated the structures of metal nanoparticles energy levels, the energy splitting of electrons around Fermi-level which is different from the Kubo theory and the new formula for computing metal nanoparticles size. The theory can explain much known phenomenon. Additionally, the relevant experiments presented in the paper have elementarily verified the correctness of the theory.更多还原
