Abstract

Check the metadata sheet to make sure that the header information, especially author names and the corresponding affiliations are correctly shown. • Check the questions that may have arisen during copy editing and insert your answers/ corrections. • Check that the text is complete and that all figures, tables and their legends are included. Also check the accuracy of special characters, equations, and electronic supplementary material if applicable. If necessary refer to the Edited manuscript. • The publication of inaccurate data such as dosages and units can have serious consequences. Please take particular care that all such details are correct. • Please do not make changes that involve only matters of style. We have generally introduced forms that follow the journal's style. Substantial changes in content, e.g., new results, corrected values, title and authorship are not allowed without the approval of the responsible editor. In such a case, please contact the Editorial Office and return his/her consent together with the proof. • If we do not receive your corrections within 48 hours, we will send you a reminder. • Your article will be published Online First approximately one week after receipt of your corrected proofs. This is the official first publication citable with the DOI. Further changes are, therefore, not possible. • The printed version will follow in a forthcoming issue.

Correlation between in situ structural and optical characterization of the semiconductor-to-metal phase transition of VO2 thin films on sapphire

“…Vanadium dioxide thin films were realized by pulsed laser deposition (PLD) onto 2 cm x 2 cm sapphire substrates at the oxygen pressure of 10 −2 mbar and temperature of 550 • C. Three VO 2 layers with different thicknesses were deposited: 135 nm (sample S1), 90 nm (sample S2) and 45 nm (sample S3). The PLD system employed is described in details elsewhere 52,53 . It uses a Qswitched tripled Nd:YAG laser (Quantel mod.…”

Analysis of Transition Metal Oxides based Heterojunction Solar Cells with S-shaped J-V curves

“…Before deposition, the substrates were cleaned by ultrasonic bath in acetone for 10 min and then rinsed in isopropyl alcohol and dried up with compressed air. The PLD employed system is described elsewhere [11] and includes a Q-switched tripled Nd:YAG laser (Quantel mod. YG78C20; λ = 355 nm) generating 6 ns width pulses with an energy of 80 mJ per pulse.…”

Large-area polycrystalline α-MoO3 thin films for IR photonics

“…The PLD system employed uses a Q-switched tripled Nd:YAG laser (Quantel mod. YG78C20, λ = 355 nm) generating 6 ns width pulses with an energy of 80 mJ per pulse [33,34,36]. The density of energy was maintained at 1.2 J cm −2 , and the repetition rate was 4 Hz.…”
