Publikováno v: Surface Science. :664-670

The adsorption of benzene and toluene on Si(1 1 1)7 × 7 was investigated using scanning tunneling microscopy (STM) and theoretical calculations. For both aromatic molecules, bright spots in the STM images and populations of the subunits, each consis

Publikováno v: Surface Science. 528:242-248

Core-electron excitation has a possibility to induce selective chemical bond scission due to its special localization and selectivity. Active control of chemical bond scission was examined in photon stimulated ion desorption (PSID) of core-excited po
