Morphology of SiO2 films on Mo(112)
Atomically resolved STM image and structure model of SiO2 film
For details: Weissenrieder, Phys. Rev. Lett. 95 (2005) 076106.
Fe-doped SiO2 as 'magnetic' material
Single Fe-atoms embedded in SiO2 and STM conductance spectrum showing a Kondo resonance at the Fe position
For details: Jerratsch et al., ACS-Nano 4 (2010) 863
SiO2-film as sieve for Au, Ag and Pd-atoms
Pd-atoms penetrate SiO2 nano-pores and bind below the film, Au atoms are too big for penetration and aggregate to surface deposits (13×13nm2)
For details: S. Ulrich et al., ChemPhysChem.9 (2008) 1367.
Li-modified SiO2 as chemically active film
Li-atoms in SiO2 and Li-modified film after Au-adsorption
For details: Martinez et al. Phys. Rev. Lett. 103, 056801 (2009).
