Didden, A. (author), Battjes, H. (author), Machunze, R. (author), Dam, B. (author), Van de Krol, R. (author)In devices based on CdS, indium is often used to make Ohmic contacts. Since indium is scarce and expensive, suitable replacement materials need to be found. In this work, we show that sputtered titanium nitride forms an Ohmic contact with n-type CdS. The CdS films, deposited with chemical bath deposition, have a hexagonal crystal structure and...journal article 2011

Leegwater, H. (author), Schut, H. (author), Egger, W. (author), Baldi, A. (author), Dam, B. (author), Eijt, S.W.H. (author)We obtained evidence for the partial chemical segregation of as-deposited and hydrogenated Mg1?yTiy films (0 ? y ? 0.30) into nanoscale Ti and Mg domains using positron Doppler-broadening. We exclusively monitor the hydrogenation of Mg domains, owing to the large difference in positron affinity for Mg and Ti. The electron momentum distribution...journal article 2010

Filippi, M. (author), Rector, J.H. (author), Gremaud, R. (author), Van Setten, M.J. (author), Dam, B. (author)We report the preparation of sodium alanate, a promising hydrogen storage material, in a thin film form using cosputtering in a reactive atmosphere of atomic hydrogen. We study the phase formation and distribution, and the hydrogen desorption, with a combination of optical and infrared transmission spectroscopy. We show that the hydrogen...journal article 2009

Prokhorov, V.G. (author), Hyun, Y.H. (author), Park, J.S. (author), Kim, J.B. (author), Kim, G.H. (author), Lee, Y.S. (author), Lee, Y.P. (author), Svetchnikov, V.L. (author)The microstructural and magnetic properties of amorphous, nanoclustered, and self-organized bilayer Nd0.5Sr0.5MnO3 films, prepared by rf magnetron sputtering, are investigated. The amorphous film was found to be a typical paramagnet with free motion of the individual Mn spins, and the magnetic properties are well described on the basis of the...journal article 2008

Gao, J.R. (author), Hajenius, M. (author), Tichelaar, F.D. (author), Klapwijk, T.M. (author), Voronov, B. (author), Grishin, E. (author), Gol'tsman, G. (author), Zorman, C.A. (author), Mehregany, M. (author)The authors have realized NbN (100) nanofilms on a 3C-SiC (100)/Si(100) substrate by dc reactive magnetron sputtering at 800?°C. High-resolution transmission electron microscopy (HRTEM) is used to characterize the films, showing a monocrystalline structure and confirming epitaxial growth on the 3C-SiC layer. A film ranging in thickness from 3.4...journal article 2007
