Phase Change Materials (PCMs) are unique compounds employed in non-volatile random access memory thanks to the rapid and reversible transformation between the amorphous and crystalline state that display large differences in electrical and optical properties. In addition to the amorphous-to-crystalline transition, experimental results on polycrystalline(More)
The phase transition from pure Ni to Ni<sub>2</sub>Si and NiSi was studied by in situ Transmission Electron Microscopy analyses from room temperature to 260degC. The reaction starts at 180degC with the formation of small Ni<sub>2</sub>Si transrotational domains. Their density and size increase by increasing the annealing temperature to 260degC. After 50(More)

The formation of pseudoepitaxial transrotational structures has been observed during the early stage of the reaction of thin Ni layers on [001] Si substrates. During the reaction, large Ni(2)Si domains, characterized by single bending contours, establish a close relationship with the silicon lattice. The silicide domain consists of a core region, along the(More)
The morphology of gold nanoparticles (AuNPs) deposited on a (100) silicon wafer by simple immersion in a solution containing a metal salt and hydrofluoric acid (HF) is altered by HF treatment both before and after deposition. The gold clusters are characterized by the presence of flat regions and quasispherical particles consistent with the layer-by-layer(More)
In this article, a scanning probe method based on nanoscale capacitance measurements was used to investigate the lateral homogeneity of the electron mean free path both in pristine and ion-irradiated graphene. The local variations in the electronic transport properties were explained taking into account the scattering of electrons by charged impurities and(More)
