چکیده

The structure of a thin single crystalline SiO(2) film grown on Mo(112) has been studied by scanning tunneling microscopy, infrared reflection absorption spectroscopy, and x-ray photoelectron spectroscopy. In excellent agreement with the experimental results, density functional theory calculations show that the film consists of a two-dimensional network of corner sharing [SiO(4)] tetrahedra, with one oxygen of each tetrahedron binding to the protruding Mo atoms of the Mo(112) surface.

On the geometrical and electronic structure of an ultra-thin crystalline silica film grown on Mo(112)

The atomic structure of a well-ordered silica film grown on a Mo(112) single crystal substrate is discussed in detail using the experimental and theoretical results available to date. New photoelectron spectroscopy results using synchrotron radiation and ultraviolet spectroscopy data are presented. The analysis unambiguously shows that the ultra-thin silica film consists of a two-dimensional ne...

Modeling zeolites with metal-supported two-dimensional aluminosilicate films.

Zeolites are one of the most widely used materials in heterogeneous catalysis. However, the current understanding of the relation between structure and reactivity of these complex and highly porous materials mostly comes from studies employing bulk-sensitive techniques and from theoretical calculations based on educated assumptions about the inner surface within the pores present in the framewo...

Structure of thin SiO2 films grown on Mo„112..

Ultra-thin SiO2 films were prepared by evaporating Si onto a Mo~112! surface followed by oxidation and annealing up to 1200 K. The surface structure and film quality were investigated by low-energy electron diffraction ~LEED!, Auger spectroscopy ~AES!, and high-resolution electron energy loss spectroscopy ~HREELS!. A well-ordered, monolayer Mo(112)-c(232)-SiO2 structure was characterized by HRE...

The structure of monolayer SiO2 on Mo(112): A 2-D [Si–O–Si] network or isolated [SiO4] units?

In this letter, atomically resolved scanning tunneling microscopic (STM) images obtained from monolayer SiO2/Mo(112) are presented. The results are consistent with a previously proposed structural model of isolated [SiO4] units based on vibrational features observed by high-resolution electron energy loss spectroscopy (HREELS) and infrared reflection–absorption spectroscopy (IRAS), and oxygen s...
