Cr/CrN nano-multilayers have been produced by varying the period and the degree of unbalancing in a magnetron sputtering system in order to study the influence of these parameters in the electrical properties. X-ray Diffraction (XRD) was used to investigate the microstructure characteristics of the multilayers and the Four Point Probe (FPP) technique in the Van der Pawn mode was used to evaluate electrical...
Nano-layered films of Cu/Cu(Zr)/Zr(Ge) and Cu/Cu(Zr) were deposited on the Si/SiOC:H substrates by magnetron sputtering. Samples were subsequently annealed at temperatures ranging from 350~500??C in vacuum, and characterized by four-point probe technique, glancing incident angle X-ray diffraction, Auger electron spectroscopy (AES) and transmission electron microscopy. The results indicated that the...
This paper reports the grown of Ni/Cu multilayers on Si monocrystalline substrates and shows some polarization investigations of Si(100) substrates. Nano structural characterization of the multilayers by high angle X-ray diffraction (XRD) and high temperature X-ray diffraction (HT-XRD) also have been presented. Annealed Ni/Cu multilayers on Si(100) substrate has been reported. The main purpose of...
Bulk nanostructured (Bi,Sb)2Te3 compounds and GeTe based amorphous/nanocrystal composites have been successfully fabricated by the combined hydrothermal/hot-pressing and quenching/annealing methods, respectively. The (Bi,Sb)2Te3 nanopowders synthesized by hydrothermal method exhibit a hollow-like structure. After hot-pressing, the nanoscale grains varying from tens to hundreds of nanometers were found...
Nanostructuring is one of the effective approaches to lower the thermal conductivity of materials. Nanostructured skutterudite-related compounds CoSb3, Fe0.5Ni0.5Sb3, Fe0.25Ni0.25Co0.5Sb3 and Te-doped CoSb3 were synthesized by a solvothermal route. The bulk materials were prepared by hot pressing or spark plasma sintering from the solvothermally synthesized nanopowders. The thermal conductivity values...
