In this letter we report the observation of surface segregation of gold from Au[sub x]Si[sub 1-x] alloys with 0.25 < x < 0.5. in view of the observed Au segregation and the known ability of gold-rich alloys to oxidize readily at tow temperature, we propose a mechanism for oxidation of silicon in Au[sub x]Si[sub 1-x] alloys with 0.4 < x < 0.7.

    The effect of single-step annealing at 450, 650, and 1000 °C under gigapascal hydrostatic pressures on oxygen segregation from Czochralski silicon samples was investigated. It was shown that the effect of applied pressure on the oxygen segregation processes begins to be detectable at 650...

    A method for determination of surface segregation during molecular-beam epitaxy is proposed. At constant beam fluxes, the temperature is switched which causes a segregation-dependent doping profile. The segregation ratio is extracted from the integrated profile avoiding problems with limited...

    Segregation of boron on ${\rm Si}(111)(\sqrt{3} \times \sqrt{3}){\rm R}30^{\circ}$ surface has been studied using the periodical calculations within the local density approximation. The obtained segregation energy (enthalpy) of about -1.9 eV is close to the published data of experimental studies...

    Experimental evidence is provided that gettering of iron by polycrystalline silicon (polysilicon) is driven by a combination of two gettering mechanisms, segregation and relaxation. The segregation coefficient of iron in polysilicon in samples annealed at temperatures between 1020 and 1175 °C...

    Using ab initio density function theory total energy calculations, we have investigated the mechanism of Fe segregation into Si Σ5(310) grain boundary (GB). We find that the segregation is site selective at the GB-Fe will only segregate to specific sites. We further find that the choice of...
