چکیده

X-ray standing wave measurements, along with local-density molecular cluster calculations, were used to determine the surface structure of the low-coverage Bi/Si~001! surface. The 232 Bi phase, predicted by theory to be the stable low-coverage structure, was found experimentally to be a metastable phase and was observed to have a thermally activated irreversible phase transition to the stable 132 phase. These measurements represent another approach for investigating the kinetics of surface reactions. @S0163-1829~96!04532-8#

First - principles study of adsorption and diffusion on Ge / Si ( 001 ) - ( 2 · 8 ) and Ge / Si ( 105 ) - ( 1 · 2 ) surfaces

Using first-principles total-energy calculations, we have investigated the adsorption and diffusion of Si and Ge adatoms on Ge/ Si(001)-(2 · 8) and Ge/Si(105)-(1 · 2) surfaces. The dimer vacancy lines on Ge/Si(001)-(2 · 8) and the alternate SA and rebonded SB steps on Ge/Si(105)-(1 · 2) are found to strongly influence the adatom kinetics. On Ge/Si(001)-(2 · 8) surface, the fast diffusion path i...

Hydrogen Induced Si Surface Segregation on Ge-Covered Si(001)

Using Fourier transform infrared-attenuated total reflectance spectroscopy in conjunction with hydrogen adsorption to probe surface layer composition, we observe a reversible place exchange between Ge and Si on Ge-covered Si(001) when the surface is dosed with atomic H at elevated temperatures. First-principles calculations confirm a thermodynamic driving force for this place exchange. To expla...

Atomic and electronic structure of Sr / Si ( 001 ) - ( 2 · 2 )

The adsorption of Sr on the Si(001) surface with the semiantiphase dimer (2 · 2) reconstruction is studied, based upon the ab initio pseudopotential calculations. It is calculated that the semiantiphase dimer (2 · 2) reconstruction (2 dimers per unit cell) is more favorable than the (2 · 1) phase (1 dimer per unit cell) by an energy of about 0.24 eV/dimer. Considering the energetically more sta...

Oxygen surface exchange kinetics of erbia-stabilized bismuth oxide

The surface oxygen exchange kinetics of bismuth oxide stabilized with 25 mol% erbia (BE25) has been studied in the temperature and pO2 ranges 773–1,023 K and 0.1– 0.95 atm, respectively, using pulse-response O–O isotope exchange measurements. The results indicate that BE25 exhibits a comparatively high exchange rate, which is rate determined by the dissociative adsorption of oxygen. Defect chem...

Si(001):B gas-source molecular-beam epitaxy: Boron surface segregation and its effect on film growth kinetics

B-doped Si~001! films, with concentrations CB up to 1.7310 22 cm, were grown by gas-source molecular-beam epitaxy from Si2H6 and B2H6 at Ts5500– 800 °C. D2 temperature-programed desorption ~TPD! spectra were then used to determine B coverages uB as a function of CB and Ts . In these measurements, as-deposited films were flash heated to desorb surface hydrogen, cooled, and exposed to atomic deut...
