cu(in,ga)se2 thin films (cigs) on metallic substrate (titanium, molybdenum, aluminum, stainless steel) were prepared by a two-step selenization of co-evaporated metallic precursors in se-containing environment under n2 gas flow. structural properties of prepared thin film were studied. to characterize the optical quality and intrinsic defect nature low-temperature photoluminescence, were perfor...

Few-layer graphene (FLG) has been predicted to exist in various crystallographic stacking sequences, which can strongly influence the material's electronic properties. We demonstrate an accurate and efficient method to characterize stacking order in FLG using the distinctive features of the Raman 2D-mode. Raman imaging allows us to visualize directly the spatial distribution of Bernal (ABA) and...

In this study, commercial-grade NiCr (80 wt % Ni, 20 wt % Cr) and NiCrSi (55 wt % Ni, 40 wt % Cr, 5 wt % Si) were used as targets and the sputtering method was used to deposit NiCr and NiCrSi thin films on Al₂O₃ and Si substrates at room temperature under different deposition time. X-ray diffraction patterns showed that the NiCr and NiCrSi thin films were amorphous phase, and the field-effect s...
