We have carried out a comprehensive experimental study of the Si(001) c(4×4) surface reconstruction by scanning tunneling microscopy (STM) (at room temperature and elevated temperatures), Auger electron spectroscopy (AES), reflection high-energy ele

We have developed a new method to estimate the permeation coefficient of gases through polymer membranes. A fixed volume of gas is put in a gas cell and introduced into ultrahigh vacuum. After positioning the gas cell to face a quadrupole mass spectr

A mass spectrometric method has been used to study transmission of noble gases (He, Ne, Ar, Kr, Xe) through thin polymer membranes of OPP and PET. The transmission of gas originating from a confined volume in a gas cell through the membrane is measur

Non-stoichiometric TiO2 forms a range of crystalline structures known as Magneli phases TinO2n−1. TiO2(110) single crystals have been annealed and the surface structure was investigated by scanning tunnelling microscopy (STM). From the surface topo

The pressure-dependent permeation of heavy noble gases through oriented polypropylene (OPP) is explained with a phenomenological model based on the hopping- like migration of particles over a network of trapping sites with random site energies. The m

Nanostructures on TiO 2 and CeO 2 have been created by treatment under ultrahigh vacuum conditions. Crystallographic shear in the bulk of rutile TiO 2 leads to line structures on the (110) surface. Regular trenches have been observed after calcium se

We have studied the atomic structure of the CeO 2 (0 0 1) surface as an example for a polar “type III” surface by scanning tunnelling microscope (STM), low energy electron diffraction (LEED) and atomistic simulation. High resolution STM on single

A self-organized network structure has been discovered after annealing TiO2(001) rutile single crystals under non-equilibrium conditions. This novel structure appears after annealing under ultrahigh vacuum conditions to above 1000°C and subsequent q
