An Investigative Study of Surface Interaction and Reaction on (2X1)platinum(110)
… of CO on (2 x 1)Pt(110) using both EELS and UV/HREELS shows that electronic transitions are shifted compared to those of gas phase. Careful analysis reveals that these shifts are caused by sigma-donation and pi-back donation between CO and the surface, confirming the Blyholder model, which has …

The adsorption of molecular oxygen on Au/Ni(111) alloys and its oxidation of CO at 85 K
… resolution electron energy loss spectroscopy (HREELS). The concentrations and frequencies of these species are determined as a function of Au coverage. The concentrations and frequencies of dissociatively chemisorbed molecular oxygen below 0.3 ML Au are measured using HREELS. A Monte Carlo …

Über den Einfluß von Oberflächendefekten auf Molekülschwingungen von Ethen auf der Kupfer(111)-Oberfläche : Schwingungsspektroskopische Untersuchung mit Elektronen und Infrarotlicht
… Elektronen-Energieverlustspektroskopie (HREELS) untersucht. Dabei konnte gezeigt werden, daß im Infrarotspektrum beobachtete Raman-aktive Schwingungen des Ethens an Defekte der Cu(111)-Oberfläche gebunden sind. Eine unerwartet große Intensitätsabschwächung der infrarotaktiven Schwingung …

Dynamics of hydrogen and low concentration carbon on Au-Ni(111) surface alloys
… resolution electron energy loss spectroscopy (HREELS). Hydrogen atoms bind relatively strongly to threefold hollow sites consisting only of Ni atoms, with a binding energy of 63 kcal/mol and characteristic vibrational frequencies of 970 and 1170 cm-¹. Hydrogen atoms bind relatively weakly to …

SURFACE SCIENCE APPROACH TO ATOMIC LAYER DEPOSITION CHEMISTRY
Recently, atomic layer deposition (ALD) has been employed as a promising technique for the growth of solid thin films with high conformality on complex geometries such as heterogeneous catalysts and microelectronic devices. In this work, surface sensitive characterization techniques have been …
