摘　　要：The Kondo effect in two-dimensionai manganese phthalocyanine （MnPc） self-assembled monolayer films on P5（111） islands is studied by low-temperature scanning tunneling microscopy. Variation of the Kondo temperature from 50 K to 300 K at different molecule adsorption sites is revealed. It is shown that the variation is mainly due to the change in the width of d orbital, rather than the shift of its energy. The two-dimensional dI/dV mapping reveals the periodic modulation of the Kondo resonance in the self-assembled MnPc monolayer.The Kondo effect in two-dimensionai manganese phthalocyanine （MnPc） self-assembled monolayer films on P5（111） islands is studied by low-temperature scanning tunneling microscopy.
