Superparamagnetic self-ordered  Ni-Silicides nanostructures on vicinal Si(111) template : new pathways to high-density magnetic memory storage devices and spintronic applications. [more details: see ref. 37 in publications List]

Self-ordered Superparamagnetic alpha-FeSi2 Nano-Stripes on vicinal Si(111) template : a anomalous magnetic behavior >> radically different from non-magnetic bulk alpha-FeSi2 phase >>> new pathways to high-density magnetic memory storage devices and spintronic applications. [more details: see ref. 24 in publications List]

Superparamagnetic self-ordered alpha-FeSi2 Nanostructures on vicinal Si(111) template: a anomalous magnetic behavior >> radically different from non-magnetic bulk alpha-FeSi2 phase >>> new pathways to high-density magnetic memory storage devices and spintronic applications [more details: see ref. 23 in publications List]

Self-ordered Ti- and Co-silicide nanoislands on vicinal Si(111) template as a function of the initial metal coverage: while a degree of this kind of SO for Co-silicide islands was higher than for the Ti-silicide ones, for both types of islands an inverse dependence of order parameter on coverage was found [more details, see ref. 20 in Publication List].

First evidence of the "Electronic growth" in Ti- and Co-silicide heterostructures on Si(111) : based on STM and scanning tunneling spectroscopy (STS) measurements, at RT, of heteroepitaxial island height distributions and density of states (DOS), respectively, we demonstrated the first evidence of the "Electronic Growth" in Ti- and Co-silicide heterostructures on Si(111) (more details,  ref. 18 in Publication List].
