In this work, gallium oxide thin films were deposited via radio frequency (RF) sputtering, using a liquid Ga target. The reactive sputtering was carried out using different oxygen flow rates and DC target potentials induced via the RF power. The thickness of the samples varied between 160 nm and 460 nm, depending on the preparation conditions. The composition and the refractive index of the layers were investigated via energy-dispersive spectroscopy, X-ray photoelectron spectroscopy, and spectroscopic ellipsometry, respectively. It was found that, through the use of a lower DC target potential, a better film quality and higher oxygen content can be achieved. The reactive sputtering was modeled based on the Berg model, with the aim of determining the sputtering yields and the sticking coefficient. It was shown that an increase in DC target potential leads to the preferential sputtering of gallium.}, keywords = {Reactive sputtering; thin film; gallium oxide; liquid gallium}, year = {2023}, eissn = {2079-6412}, orcid-numbers = {Gajdics, Marcell/0000-0002-1891-7381; Serényi, Miklós/0000-0003-4684-3452; Kolonits, Tamás/0000-0002-5836-4398; Horváth, Zsolt Endre/0000-0002-4632-0136; Pécz, Béla/0000-0002-4651-6972} } @article{MTMT:34094001, title = {A modified plasma immersed solid-phase impurity assisted doping geometry for the creation of highly fluorescent CVD nanodiamond}, url = {https://m2.mtmt.hu/api/publication/34094001}, author = {Himics, László and Gál, Dávid and Csíkvári, Péter and Holomb, Roman and Koós, Margit and Sulyok, Attila and Pécz, Béla and Veres, Miklós}, doi = {10.1016/j.vacuum.2023.112493}, journal-iso = {VACUUM}, journal = {VACUUM}, volume = {216}, unique-id = {34094001}, issn = {0042-207X}, abstract = {In this work, we report on a simple and easy to realize doping geometry by which the color center formation efficiency can be improved significantly in nanocrystalline diamond structures during solid impurity source-assisted microwave plasma enhanced chemical vapor deposition (MWCVD). A vertically aligned solid impurity source immersed into the CVD plasma results in diamond thin film with significantly higher color center related fluorescence signal, than the horizontal and source-free arrangements. Based on the example of negatively charged silicon-vacancy (SiV−) center, we demonstrated that the emission peak intensity of fluorescent nanodiamond structures prepared in such a way can be 7–10 times enhanced without significant alteration of the crystal quality. The observed phenomenon is explained by the increased number of incorporated silicon impurities into the diamond nanocrystals, initiated by the beneficial conditions for the atomization of the vertically aligned impurity source, including the enlarged contact area and the elevated surface temperature. The efficiency of the method was demonstrated for thin films and individual nanocrystal structures as well. The proposed solid-phase doping source geometry can be adapted to other impurities to extend the type or improve the in-situ formation efficiency of impurity related color centers in CVD nanodiamond crystals.}, keywords = {Fluorescent nanodiamond; Impurity-related color centers; Increased photoluminescence signal; Solid impurity source-assisted doping; Microwave plasma enhanced chemical vapor deposition}, year = {2023}, eissn = {1879-2715}, orcid-numbers = {Gál, Dávid/0000-0002-0661-8544; Pécz, Béla/0000-0002-4651-6972} } @article{MTMT:33733765, title = {In-situ formation of Ag nanoparticles in the MAO coating during the processing of cp-Ti}, url = {https://m2.mtmt.hu/api/publication/33733765}, author = {Maj, Ł. and Fogarassy, Zsolt and Wojtas, D. and Jarzębska, A. and Muhaffel, F. and Sulyok, Attila and Góral, A. and Kulczyk, M. and Çimenoğlu, H. and Bieda, M.}, doi = {10.1038/s41598-023-29999-7}, journal-iso = {SCI REP}, journal = {SCIENTIFIC REPORTS}, volume = {13}, unique-id = {33733765}, issn = {2045-2322}, year = {2023}, eissn = {2045-2322}, orcid-numbers = {Fogarassy, Zsolt/0000-0003-4981-1237} } @article{MTMT:33706376, title = {Energy loss function of samarium}, url = {https://m2.mtmt.hu/api/publication/33706376}, author = {Yang, T.F. and Zeng, R.G. and Yang, L.H. and Sulyok, Attila and Menyhárd, Miklós and Tőkési, Károly and Ding, Z.J.}, doi = {10.1038/s41598-023-30770-1}, journal-iso = {SCI REP}, journal = {SCIENTIFIC REPORTS}, volume = {13}, unique-id = {33706376}, issn = {2045-2322}, year = {2023}, eissn = {2045-2322}, orcid-numbers = {Menyhárd, Miklós/0000-0003-4581-5337; Tőkési, Károly/0000-0001-8772-8472} }
