Co nanoislands on Au(111) and Cu(111) surfaces studied by scanning tunneling microscopy and spectroscopy.
Co nanoislands on the Au(111) and Cu(111) surfaces have been studied by scanning tunneling microscopy and spectroscopy. The experimental results showed that Co nanoislands prefer to aggregate at the step edge and dislocation sites on the reconstructed Au(111) surface and at the step edge on the Cu(111) surface, respectively. In addition, based on dZ/dV-V spectra, in both the Co/Au(111) and the ...
متن کاملCopper-on-copper homoepitaxy studied by infrared spectroscopy of adsorbed CO.
Infrared spectroscopy of adsorbed CO was used to characterize the dependence of surface structure on deposition temperature during homoepitaxial growth on Cu(100). Intensity borrowing due to dipole coupling greatly enhances the absorption signal due to defect-bonded CO, making it possible to detect and quantify defect concentrations at the level of a few percent. For deposition temperatures bet...
متن کاملNih-3T3 Fibroblast Studied by Fourier Transform Infrared Spectroscopy
In this work I present the study of the behaviour response of mouse broblasts NIH-3T3 under UVB radiation using Fourier transform infrared spectroscopy (FT-IR), the preferred method of infrared spectroscopy. FT-IR, in fact, it is convenient to study molecular cell processes because it has the potential to provide the identi cation of the vibrational modes of some of the major compounds (lipid, ...
متن کاملPhotoexcited GaAs surfaces studied by transient terahertz time-domain spectroscopy.
The transmission characteristics of an air-GaAs interface and the transient absorption and index spectra of the thin, photoexcited surface layer are investigated subsequent to excitation by a femtosecond laser pulse. We find that the total phase change and transmission of a terahertz (THz) probe pulse are dominated by interface effects. This observation has important implications in the interpr...
متن کاملInfrared spectroscopy of molecular submonolayers on surfaces by infrared scanning tunneling microscopy: tetramantane on Au111.
We have developed a new scanning-tunneling-microscopy-based spectroscopy technique to characterize infrared (IR) absorption of submonolayers of molecules on conducting crystals. The technique employs a scanning tunneling microscope as a precise detector to measure the expansion of a molecule-decorated crystal that is irradiated by IR light from a tunable laser source. Using this technique, we o...
