Growth of Cr on Cu(001) studied by scanning tunneling microscopy

Metal-silicene interaction studied by scanning tunneling microscopy.

Ag atoms have been deposited on 3  ×  3 silicene and  √3  ×  √3 silicene films by molecular beam epitaxy method in ultrahigh vacuum. Using scanning tunneling microscopy and Raman spectroscopy, we found that Ag atoms do not form chemical bonds with both 3  ×  3 silicene and  √3  ×  √3 silicene films, which is due to the chemically inert surface of silicene. On 3  ×  3 silicene films, Ag atoms mo...

Adsorption and Reactions of Water on the Copper (110) Surface Studied by Scanning Tunneling Microscopy By

Adsorption of diferrocenylacetylene on Au(111) studied by scanning tunneling microscopy.

Scanning tunneling microscopy images of diferrocenylacetylene (DFA) coadsorbed with benzene on Au(111) show individual and close-packed DFA molecules, either adsorbed alongside benzene or on top of a benzene monolayer. Images acquired over a range of positive and negative tip-sample bias voltages show a shift in contrast, with the acetylene linker appearing brighter than the ferrocenes at posit...

Coadsorption phases of CO and oxygen on Pd(111) studied by scanning tunneling microscopy

The adsorption of CO on an oxygen precovered Pds111d surface was investigated between 60 and 300 K. Applied methods were variable temperature scanning tunneling microscopy sSTMd and video STM to analyze the coadsorption structures. The STM data are compared with simulated STM images for the various surface phases in order to identify the appropiate structural model for each case. Low-energy ele...

Initial stages of Pt growth on Ge„001... studied by scanning tunneling microscopy and density functional theory

We have studied the initial stages of submonolayer Pt growth on the Ges001d. We have observed several stable and meta-stable adsorption configurations of Pt atoms at various temperatures. Calculations indicate relatively high binding energies of Pt atoms onto the Ge lattice, at different adsorption sites. Our results show that through-the-substrate bonding (concerted bonding) of two Pt atoms is...
