Abstract
The interaction of Ti(110) with , , CO, and C was studied by means of low-energy electron diffraction, x-ray photoelectron spectroscopy, electron energy-loss spectroscopy, thermal desorption, electron paramagnetic resonance, and measurements of changes in surface conductivities, , and work functions, , for K with particular emphasis on surface reactions involving intrinsic surface defects . The defects are thermodynamically stable at high temperatures and act as donors and specific adsorption sites for and CO. Surface and subsurface reactions involving , , CO, and C can be separated from each other by analyzing the and effects in a charge-transfer model, which takes into account surface and bulk electronic states in the band gap attributed to the different defects formed during the interaction.
