مطالعه سطح Ni(001) با استفاده از محاسبه منحنی های I/E در روش (LEED)

The rcnccted beam intensity as a lunctlon of dcclron energy ( lIE curve) is studied for an ideal (001) Ni surface by low energy electron diffraction (LEED). Double layer method, rcnormalized forward scattering (RFS) and quasi-dynamic method arc used for lIE curves calculation. The role of structural and nonstructural parameters of Ni on lIE curves is examined. The crfect or the optical p...

Adsorption processes of hydrogen molecules on SiC(001), Si(001) and C(001) surfaces

Adsorption processes of hydrogen molecules on the Si(001)-(2× 1) and C(001)-(2× 1) surfaces are discussed in light of our previous studies of H2 adsorption on the related SiC(001)-c(4× 2) surface. Very amazingly, there are pathways above the latter on which hydrogen molecules can adsorb dissociatively at room temperature. One of these pathways has not been considered before for adsorption of H2...

Unexpected resonant response in [Fe(001)/Cr(001)]10/MgO(001) multilayers in a magnetic field.

We observed unexpected resonant response in [Fe/Cr]10 multilayers epitaxially grown on MgO(100) substrates which exists only when both ac current and dc magnetic field are simultaneously applied. The magnitude of the resonances is determined by the multilayer magnetization proving their intrinsic character. The reduction of interface epitaxy leads to nonlinear dependence of the magnitude of res...
