| 英文摘要 | here we present direct observation of a quantum reactivity with respect to the amounts of o(2) adsorbed and the rates of surface oxidation as a function of film thickness on ultrathin (2-6 nm) pb mesas by scanning tunneling microscopy. simultaneous spectroscopic measurements on the electronic structures reveal a quantum oscillation that originates from quantum well states of the mesas, as a generalization of the fabry-perot modes of confined electron waves. we expect the quantum reactivity to be a general phenomenon for most ultrathin metal films with broad implications, such as nanostructure tuning of surface reactivities and rational design of heterogeneous catalysts. |
