Femtosecond ultraviolet laser-induced desorption of NO from NiO(100)/Ni(100)

Abstract: We have studied the ultraviolet laser-induced desorption of NO molecules from an epitaxial film of NiO(100) on Ni(100) for pulse durations of 550 fs and at a photon energy of 3.95 eV. For applied laser intensities up to 450 MW/cm2, the highest intensities employed in this work, a linear dependence of the desorption yield on the laser intensity is observed. A desorption cross section of (1.9±0.3)⋅10−17 cm2 is then derived. The molecules are detected with rovibrational state selectivity by (1+1)-REMPI via the A … Show more

“…In particular, a microscopic description of the dissipation has not been attempted so far. We therefore combine the information from previous studies 4,11,39,40,42,43 with the surrogate Hamiltonian method 2,3 to develop a model which treats the nuclear dynamics as well as the excitation and relaxation mechanism on the same level of rigor.…”

“…2 a 3 transition in the CO molecule in gas phase, as the crucial excitation step in laser-induced desorption [14]. This is in contrast to the NO-NiO(100) system, where a charge transfer state, resulting in an NO ÿ -NiO species, is the decisive excited state [1] in similar photoinduced desorption experiments [15,16]. To verify whether a 5 !…”
