Carbon depth profiling of superconducting YBCO thin films on nanometer scale

Autor: Nicholas J. Long, Andrea Bubendorfer, Andreas Markwitz, N Dytlewski, V.J. Kennedy

Publikováno v: Current Applied Physics. 4:292-295

Ion beam analysis techniques have been used to probe for carbon contamination in high temperature superconductor thin films. These techniques provide a powerful tool to detect C with limit of detection close to 0.01 at.% and to measure carbon depth p

Large-grain polycrystalline silicon thin films obtained by low-temperature stepwise annealing of hydrogenated amorphous silicon

Autor: Ricardo Rüther, N. Dytlewski, John Livingstone

Publikováno v: Scopus-Elsevier

Large grained polycrystalline silicon thin films have been prepared by low-temperature solid phase crystallisation of sputter-deposited hydrogenated amorphous silicon (a-Si:H), with relatively short processing times, and a considerably low thermal bu

Improved hydrogen depth profiles with in‐chamber annealing of hydrogenated amorphous silicon thin films

Autor: Ricardo Rüther, John Livingstone, N. Dytlewski, D. Cohen

Publikováno v: Scopus-Elsevier

We have undertaken a study on the influence of deposition temperature and an in‐chamber annealing treatment on the hydrogen depth profiles of sputter‐deposited hydrogenated amorphous silicon (a‐Si:H) thin films. Our results show that for higher

Bond switching, Si-H cluster formation and hydrogen effusion upon thermal annealing in hydrogenated amorphous silicon thin films

Autor: Ricardo Rüther, N. Dytlewski, D. Cohen, John Livingstone

Publikováno v: Thin Solid Films. 271:151-156

Hydrogenated amorphous silicon (a-Si:H) thin films deposited by the reactive-sputtering technique and, in some cases, indashsitu annealed were subjected to further thermal annealing steps to 600 °C. Elastic recoil detection analysis measurements ind

Comparison of neutron and electron irradiation on the EL2 defect in GaAs

Autor: L. Faraone, Brett Nener, T. C. Ku, Dimitri Alexiev, N. Dytlewski, S.T. Lai

Publikováno v: Journal of Applied Physics. 77:2985-2988

The deep level transient spectroscopy technique has been used to study the EL2 defect in n‐type semiconducting GaAs subjected to 1 MeV fast neutrons at room temperature. After neutron irradiation, the EL3 defect which is usually detected between 18

Measurement variances in thermal neutron coincidence counting

Autor: M.S. Krick, N. Dytlewski, N. Ensslin

Publikováno v: Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment. 327:469-479

Methods are presented for reliably estimating the uncertainties in quantities of plutonium as measured using neutron coincidence counting for nuclear safeguards purposes. For the conventional two-parameter assay technique, semi-empirical equations ar

Assay variance as a figure of merit for neutron multiplicity counters

Autor: M.S. Krick, N. Ensslin, N. Dytlewski

Publikováno v: Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment. 290:197-207

This paper describes a procedure for estimating assay variance for the neutron multiplicity counters that are being developed to assay special nuclear materials. The procedure estimates the moments of the expected neutron multiplicity distribution an
