Abstract
A new method developed to prepare a homogeneous monolayer of ω-alk-1-ene-silane-functionalized magnetite nanoparticles covalently linked to a hydrogen-terminated silicon surface by thermal hydrosilylation reaction was discussed. The morphological and the structural properties of the nanoparticles were characterized by x-ray diffractometry (XRD) and transmission electron microscopy (TEM) analysis. The nanoparticles were single crystal as evidenced by the orientation of lattice planes observed in high-resolution micrographs. The results provided clear evidence that the proposed synthetic procedure can effectively provide a uniform extended layer of particles strongly bound to the substrate
