Adsorption of CO on the (110) plane of tungsten electron impact, thermal desorption, and work function measurements

The adsorption of CO and oxygen on Cu layers on a W(110) surface

“…Coverage of CO and 0 The spectrum on clean W shows the behavior found previously, namely a virgin desorption peak at ^.400 K (somewhat higher than in the step desorption work of Leung, Vass, and Goner [6] or Kohrt and…”

Adsorption of oxygen on the (110) plane of tungsten at low temperatures

“…The sequential isotopic dosing experiment was carried out in the apparatus used by Leung and Gomer, described in detail 4 previously. 1802…”

CO Adsorption on Mo(110) Studied Using Thermal Desorption Spectroscopy (TDS) and Ultraviolet Photoelectron Spectroscopy (UPS)

“…Electron stimulated desorption (ESD) and Thermal Desorption Spectroscopy (TDS) are useful in obtaining information about adsorbate geometries; however, these methods are often regarded as rather destructive techniques, providing only indirect information. [5][6][7][8][9][10][11][12][13] Vibrational spectroscopy, such as high-resolution electron energy loss spectroscopy (HREELS) and infra-red absorption spectroscopy (IRAS), can be useful but the selection rules prohibit the detection of some molecular structures, e.g. it is difficult to observe molecularly bound CO placed parallel to the surface.…”

“…The dissociative and non-dissociative chemisorption of CO on both surfaces have been suggested using a variety of experimental and theoretical methods. 3,[5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24] Experimentally, identifying the dissociative chemisorption of CO on a solid surface is not trivial. Electron stimulated desorption (ESD) and Thermal Desorption Spectroscopy (TDS) are useful in obtaining information about adsorbate geometries; however, these methods are often regarded as rather destructive techniques, providing only indirect information.…”
