  2. 16. Vibrational Spectroscopy of Surface Adsorbates on Metal Surfaces. Experiments and Calculations

    Author : Ragnar K Ásmundsson; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ab initio electronic structure calculations; Fermi resonance; vibrational spectroscopy; Reflection absorption infrared spectroscopy; Fourier transform infrared spectroscopy; Cu 100 and W 110 single crystal surfaces; Physics; Fysik;

    Abstract : This work deals with a detailed analysis of the vibrational spectra of methoxy (CH3O-) and ethoxy (CH3CH2O-) on W(110) and Cu(100) single crystal surfaces. By using theoretical ab initio quantum mechanical modeling, it is demonstrated that an unprecedented quantitative understanding of the vibrational frequencies of a surface adsorbate can be obtained.

  6. 19. Experimental and Theoretical Studies of Metal Adsorbates Interacting with Elemental Semiconductor Surfaces

    Author : Hafiz Muhammad Sohail; Roger Uhrberg; Leif Johansson; Kevin E. Smith; Linköpings universitet; []
    Keywords : ;

    Abstract : Metal adsorbates on semiconductor surfaces have been widely studied over the last few decades. The main interest is focused on various one or two-dimensional structures that exhibit interesting electronic and atomic properties. This thesis focuses on metal adsorbates interacting with the Si(111) and Ge(111) surfaces. READ MORE
