Experimental evidence on photo-assisted O ion production from AlO cathode in cesium sputter negative ion source
O. Tarvainen, R. Kronholm, M. Laitinen +8
The production of negative ions in cesium sputter ion sources is generally considered to be a pure surface process. It has been recently proposed that ion pair production could exp…
Ti alloyed -GaO: route towards wide band gap engineering
A. Barthel, J. W. Roberts, M. Napari +6
The suitability of Ti as a band gap modifier for -GaO was investigated, taking advantage of the isostructural α-phases and high band gap difference between TiO a…
Characterization of U alpha recoil sources for Th beam production
I. Pohjalainen, I. D. Moore, T. Sajavaara
Radioactive U alpha recoil sources are being considered for the production of a thorium ion source to study the low-energy isomer in Th with high-resolution colline…
Transition-Edge Sensors for Particle Induced X-ray Emission Measurements
M. R. J. Palosaari, K. M. Kinnunen, J. Julin +10
In this paper we present a new measurement setup, where a transitionedge sensor detector array is used to detect X-rays in particle induced X-ray emission measurements with a 2 MeV…
Evidence of quantum phase slip effect in titanium nanowires
Janne Lehtinen, Timo Sajavaara, Konstantin Arutyunov +1
Electron transport properties of titanium nanowires were experimentally studied. Below the effective diameter 50 nm all samples demonstrated a pronounced broadening of t…
Influence of substrate bias on the structural and dielectrical properties of magnetron-sputtered BaxSr1-xTiO3 thin films
Tommi Riekkinen, Jan Saijets, Pasi Kostamo +2
The application of a substrate bias during rf magnetron sputtering alters the crystalline structure, grain morphology, lattice strain and composition of BaxSr1-xTiO3 thin films. As…
