Abstract: Controllable atmospheric pressure CVD has been optimized to grow transition metal dichalcogenide MoSe2 with tunable morphology at 750 °C on a silicon substrate with a native oxide layer of 250 nm. Utilizing tetrapotassium perylene-3,4,9,10-tetracarboxylate (PTAS) as a seed promoter and varying the vertical distance between the substrate and the precursor MoO3, different morphologies of MoSe2 were achieved, including 2D triangles, hexagons, 3D pyramids and vertically aligned MoSe2 sheets. We find that the shape of MoSe2 is highly dependent upon the distance h between the substrate and the precursor. The change in the morphology is attributed to the confinement of vapor (MoO3 and Se) precursors and their concentrations due to the change in h. These results are helpful in improving our understanding about the factors which influence the morphology (shape evolution) and also the continuous growth of MoSe2 films.

Abstract: This article attempts to reconstruct the literary and familial ties between the descendants of the Friulian Godeas family, one of these descendants being Alojz Gradnik. The article‘s methodological approach stems from the interpretation of the personal correspondence between the Godeas family descendants (from Trieste, Zagreb and Rosario). Based on all this, the second part of the article offers a few prompts for research on Gradnik‘s reception in Argentina, based on systemic approach to literature. We come to the conclusion that Gradnik‘s cultural hybridity allowed him to access the Argentine literary space through two cultural groups: the Slovene and Argentine.

Abstract: One order of magnitude energy enhancement of the target surface electron beams with central energy at 11.5 MeV is achieved by using a 200 TW, 500 fs laser at an incident angle of 72° with a prepulse intensity ratio of 5×10−6. The experimental results demonstrate the scalability of the acceleration process to high electron energy with a longer (sub-picosecond) laser pulse duration and a higher laser energy (120 J). The total charge of the beam is 400±20 pC(
