Journal ArticleDOI
Carbon nitride deposited using energetic species: a review on xps studies
TL;DR: In this paper, a review of x-ray photoelectron spectroscopy studies on carbon nitride (CN) is presented, based on results obtained from CN thin films prepared by mass selected ion-beam deposition.
Journal ArticleDOI
Incorporation of Zn2+ ions into BaTiO3:Er3+/Yb3+ nanophosphor: an effective way to enhance upconversion, defect luminescence and temperature sensing
Manoj Kumar Mahata,Manoj Kumar Mahata,Tristan Koppe,Tanusree Mondal,C. Brüsewitz,Kaushal Kumar,Vineet Kumar Rai,Hans Hofsäss,Ulrich Vetter +8 more
TL;DR: Ferroelectric BaTiO3 became a multifunctional material via doping of lanthanide ions and subsequently upconversion luminescence was enhanced by incorporation of Zn(2+) ions, and it is inferred that two types of Er(3+) sites are present in the barium titanate lattice.
Journal ArticleDOI
Ion implantation of graphene-toward IC compatible technologies.
Ursel Bangert,W. Pierce,Despoina-Maria Kepaptsoglou,Quentin M. Ramasse,Recep Zan,Mhairi Gass,J. A. van den Berg,Chris Boothroyd,J. Amani,Hans Hofsäss +9 more
TL;DR: Using high-angle dark field imaging (HAADF) combined with single-atom electron energy loss (EEL) spectroscopy reveals that for sufficiently low implantation energies ions are predominantly substitutionally incorporated into the graphene lattice with a very small fraction residing in defect-related sites as discussed by the authors.
Journal ArticleDOI
Cylindrical spike model for the formation of diamondlike thin films by ion deposition
TL;DR: In this article, the ion energy dependence of nT/nS was analyzed for diamond-like film growth and it was shown that nT nS>1 is the optimum condition for diamondlike films.
Journal ArticleDOI
Simulation of ion beam sputtering with SDTrimSP, TRIDYN and SRIM
TL;DR: In this paper, the authors discuss the possibilities, the key benefits and the limitations of three popular binary collision Monte Carlo simulation programs (SDTrimSP, TRIDYN and SRIM).
