Room-Temperature $^{181}$Ta(TiO$_2$): An e-γ TDPAC Study / Yap, Ian Chang Jie (Gottingen U., II. Phys. Inst.) ; Schell, Juliana (CERN ; Duisburg-Essen U.) ; Dang, Thien Thanh (Duisburg-Essen U.) ; Noll, Cornelia (Bonn U., HISKP) ; Beck, Reinhard (Bonn U., HISKP) ; Köster, Ulli (Laue-Langevin Inst.) ; Mansano, Ronaldo (Sao Paulo U.) ; Hofsäss, Hans Christian (Gottingen U., II. Phys. Inst.)
In this work, we report on the hyperfine parameters of the foreign 181Ta probe in the rutile structure of the single crystal TiO2 using the e−γ and γ−γ time differential perturbed angular correlation (TDPAC) technique. We implanted 181Hf ions into a sample of single crystal rutile TiO2 in the Bonn Isotope Separator. [...]

In and Cd as defect traps in titanium dioxide / Schell, Juliana (CERN ; Duisburg-Essen U.) ; Lupascu, Doru C (Duisburg-Essen U.) ; Martins Correia, João Guilherme (CERN ; IST, Lisbon (main)) ; Carbonari, Artur Wilson (U. Sao Paulo (main)) ; Deicher, Manfred (Saarland U.) ; Barbosa, Marcelo Baptista (Porto U.) ; Mansano, Ronaldo Domingues (U. Sao Paulo (main)) ; Johnston, Karl (CERN) ; Ribeiro, Ibere S (U. Sao Paulo (main)) /ISOLDE
We present a study of TiO$_2$ single crystals from the point of view of the dopant atom that simultaneously behaves as the probing element. We used gamma-gamma time dependent perturbed angular correlations working with selected tracer elements ($^{111}$In/ $^{111}$Cd, $^{111m}$Cd/ $^{111}$Cd) together to investigate the different behavior of Cd and In dopants, particularly their interaction with point defects in the TiO$_2$ lattice.

Implantation of cobalt in SnO2 thin films studied by TDPAC / Schell, Juliana (CERN ; U. Duisburg-Essen) ; Lupascu, Doru C (U. Duisburg-Essen) ; Carbonari, Artur Wilson (IPEN, Sao Paulo) ; Mansano, Ronaldo Domingues (U. Sao Paulo (main)) ; Dang, Thien Thanh (Bonn U., HISKP) ; Vianden, Reiner (Bonn U., HISKP)
Here we report time differential perturbed angular correlation (TDPAC) results of Co-doped SnO2 thin films. Making use of stable Co and radioactive 111In implanted at the Bonn Radioisotope Separator with energies of 80 keV and 160 keV, respectively, it was possible to study the dopant incorporation and its lattice location during annealing.

Cd and In-doping in thin film SnO2 / Schell, Juliana (CERN ; Duisburg-Essen U.) ; Lupascu, Doru C (Duisburg-Essen U.) ; Wilson Carbonari, Artur (Sao Paulo U., FFCLRP) ; Domingues Mansano, Ronaldo (Sao Paulo U., FFCLRP) ; S Freitas, Rafael (Sao Paulo U., FFCLRP) ; Nuno Gonçalves, João (Aveiro U.) ; Thanh Dang, Thien (Bonn U.) ; Vianden, Reiner (Bonn U.)
In this paper, we investigate the effects of doping in the local structure of SnO2 by measuring the hyperfine interactions at impurity nuclei using the Time Differential Perturbed Gamma-Gamma Angular Correlation (TDPAC) method in addition to density functional theory simulations. The hyperfine field parameters have been probed as a function of the temperature in thin film samples. [...]

Ion implantation in titanium dioxide thin films studied by perturbed angular correlations / Schell, Juliana (CERN ; U. Duisburg-Essen) ; Lupascu, Doru C (U. Duisburg-Essen) ; Carbonari, Artur Wilson (IPEN, Sao Paulo) ; Domingues Mansano, Ronaldo (Polytechnic School, University of São Paulo) ; Souza Ribeiro Junior, Ibere (IPEN, Sao Paulo) ; Dang, Thien Thanh (Bonn U., HISKP) ; Anusca, Irina (U. Duisburg-Essen) ; Trivedi, Harsh (U. Duisburg-Essen) ; Johnston, Karl (CERN) ; Vianden, Reiner (Bonn U., HISKP)
The local environment in titanium dioxide was studied by the time dependent perturbed $\gamma\gamma$ angular correlation of $^{111}In/^{111}Cd$ and $^{181}Hf/^{181}Ta$ at the Helmholtz-Institut fur Strahlen-und Kernphysik, Bonn. An introduction to the implantation methodologies performed at the Bonn Radioisotope Separator is presented. [...]
