Synchrotron radiation induced reactions on surfaces: mechanisms and applications

Ultraviolet and electron radiation induced fragmentation of adsorbed ferrocene

“…The photoemission and thermal desorption results can be reconciled if the ultraviolet light leads to dissociation, as has been observed for other molecular adsorbates 2,34 and gaseous substituted ferrocenes. 35 Even the partial dissociation of fer- rocene, such as the loss of hydrogen, is very likely to increase the heat of desorption and hence the desorption temperature.…”

“…2 Ferrocene, Fe͑C 5 H 5 ͒ 2 , has been one of those molecules that has been investigated for possible fragmentation following exposure to synchrotron radiation. 3 For molecular ferrocene adsorption on Si͑111͒ 2ϫ1 surfaces, exposure to unmonochromatized synchrotron light apparently only led to the partial desorption of the adsorbed species and molecular fragmentation was not observed.…”

State-selective enhanced production of positive ions and excited neutral fragments of gaseous CH2Cl2following ClLu1, Chen2, Lee3 et al. 2010Phys. Rev. A

“…The fragmentation dynamics of gaseous molecules and molecular adsorbates on surfaces excited by x-ray photons has attracted much attention because of its scientific importance and technological applications [1,2]. An understanding of x-ray-initiated molecular photolysis is an important entry for the development of evolving technology in the fabrication of microelectronic devices into the nanometer range.…”

Continuous-time photoelectron spectroscopy for monitoring monochromatic soft x-ray photodissociation of CF3Cl adsorbed on Si(111)−7×7

“…[6][7][8][9][10][11][12] Photoelectron spectroscopy ͑PES͒ has been extensively employed as a probe to investigate the electronic structure and chemical bonding of adsorbates. 1 SR-stimulated processing is a future prospective technology for low-temperature fabrication of semiconductor devices.…”
