Thin films of metallic ruthenium were grown by atomic layer deposition (ALD) in the temperature range 275–400 °C using bis(cyclopentadienyl)ruthenium (RuCp2) and oxygen as precursors. The ruthenium ...films were grown on thin Al2O3 and TiO2 films on glass. X‐ray diffraction (XRD) analysis indicated that the films were polycrystalline metallic ruthenium and scanning electron microscopy (SEM) studies showed that the films had excellent conformality. The impurity content of the films, as measured by time‐of‐flight elastic recoil detection analysis (TOF‐ERDA), were very low. All the films had resistivities below 20 μΩ cm.
Thin films of metallic ruthenium are grown by ALD in the temperature range 275–400 °C using bis(cyclopentadienyl)ruthenium and oxygen as precursors. The films are grown on thin Al2O3 and TiO2 films on glass. XRD analysis indicates that the films are polycrystalline metallic ruthenium and SEM studies shows that the films have excellent conformality. The impurity contents are very low as measured by time‐of‐flight elastic recoil detection analysis. All deposited films show resistivity below 20 μΩ cm, higher than the resistivity of the bulk metal. The resistivity of the films decreases as the deposition temperature is increased.
This paper presents a study of the production of a single W boson in association with one or more jets in proton-antiproton collisions at √s = 1.96 TeV , using the entire data set collected in ...2001–2011 by the Collider Detector at Fermilab at the Tevatron, which corresponds to an integrated luminosity of 9.0 fb−1 . The W boson is identified through its leptonic decays into electron and muon. The production cross sections are measured for each leptonic decay mode and combined after testing that the ratio of the W ( → μν ) + jets cross section to the W ( → eν ) + jets cross section agrees with the hypothesis of e -μ lepton universality. The combination of measured cross sections, differential in the inclusive jet multiplicity ( W + ≥ N jets with N = 1 , 2, 3, or 4) and in the transverse energy of the leading jet, are compared with theoretical predictions.
Our study of vector boson (V ) production in conjunction with a D*(2010)+ meson is presented. Using a data sample correponding to 9.7 fb-1 p of proton-antiproton collisions at center-of-mass energy ...√s = 1:96 TeV produced by the Fermilab Tevatron, we reconstruct V +D*+ samples with the CDF II detector. The D*+ is fully reconstructed in the D*(2010)+ → D0(→ K- π+)π+ decay mode. This technique is sensitive to the associated production of vector boson plus charm or bottom mesons. We measure the ratio of production cross sections σ(W +D*)/ σ(W) = 1.75±0.13(stat)±0:09(syst)% and σ(Z +D*)/ σ(Z) = 1:5±0:4(stat)_0:2(syst)%. Event properties are utilized to determine the fraction of V +D*(2010)+ events originating from different production processes. Our results are in agreement with the predictions obtained with the pythia program, limiting possible contribution from non-standard-model physics processes.
