Electrical properties of Ta2O5 films obtained by plasma enhanced chemical vapor deposition using a TaF5 source
Applied Physics Letters, 1996Co-Authors: R A B Devine, Laurent Vallier, Jean-luc Autran, Philippe Paillet, Jean-luc LerayAbstract:High quality Ta2O5 thin films have been obtained from TaF5 and O2 using a microwave Excited Electron cyclotron resonance plasma at low pressure (∼2 mTorr). Physical and electrical measurements reveal that the as‐deposited amorphous films have excellent properties: refractive indices ∼2.16, dielectric constants ∼25, and leakage currents

Physical and electrical measurements reveal that the as‐deposited amorphous films have excellent properties: refractive indices ∼2.16, dielectric constants ∼25, and leakage currents <10−10 A cm−2 at 2.5 V (0.3 MV cm−1, 85 nm thick, 13 nm SiO2 equivalent). Trapping and conduction properties of these layers have also been investigated, showing a reversible Electron trapping and a trap‐limited Poole–Frenkel effect.

Search for Excited Electrons and muons in sqrt(s)=8 TeV proton-proton collisions with the ATLAS detector
New Journal of Physics, 2013Co-Authors: G. Aad, S. Albrand, Q. Buat, B. Clement, J. Collot, S. Crépé-renaudin, T. Delemontex, J. Brown, B. Dechenaux, P.a. DelsartAbstract:The ATLAS detector at the LHC is used to search for Excited Electrons and Excited muons in the channel pp -> ll* -> llgamma, assuming that Excited leptons are produced via contact interactions. The analysis is based on 13 fb-1 of pp collisions at a centre-of-mass energy of 8 TeV. No evidence for Excited leptons is found, and a limit is set at the 95% credibility level on the cross section times branching ratio as a function of the Excited-lepton mass m_l*. For m_l* > 0.8 TeV, the respective upper limits on sigma*B(l* -> lgamma) are 0.75 fb and 0.90 fb for the e* and mu* searches. Limits on sigma*B are converted into lower bounds on the compositeness scale Lambda. In the special case where Lambda = m_l*, Excited-Electron and Excited-muon masses below 2.2 TeV are excluded.

Search for Excited leptons in proton-proton collisions at sqrt(s) = 7 TeV with the ATLAS detector
Physical Review D, 2012Co-Authors: G. Aad, S. Albrand, M.l. Andrieux, Q. Buat, B. Clement, J. Collot, S. Crépé-renaudin, T. Delemontex, P.a. Delsart, M.h. GenestAbstract:The ATLAS detector is used to search for Excited leptons in the electromagnetic radiative decay channel l* --> l+gamma. Results are presented based on the analysis of pp collisions at a center-of-mass energy of 7 TeV corresponding to an integrated luminosity of 2.05/fb. No evidence for Excited leptons is found, and limits are set on the compositeness scale Lambda as a function of the Excited lepton mass m_l*. In the special case where Lambda = m_l*, Excited Electron and muon masses below 1.87 TeV and 1.75 TeV are excluded at 95% C.L., respectively.

search for Excited Electrons and muons in s 8 tev proton proton collisions with the atlas detector
New Journal of Physics, 2013Co-Authors: T Abajyan, B. Abbott, M. Abolins, Ovsat Abdinov, Ossama Abouzeid, J Abdallah, Abdel S Khalek, R Aben, H Abramowicz, H AbreuAbstract:The ATLAS detector at the Large Hadron Collider is used to search for Excited Electrons and Excited muons in the channel pp → ll* → llγ, assuming that Excited leptons are produced via contact interactions. The analysis is based on 13 fb−1 of pp collisions at a centre-of-mass energy of 8 TeV. No evidence for Excited leptons is found, and a limit is set at the 95% credibility level on the cross section times branching ratio as a function of the Excited-lepton mass ml*. For ml* ≥ 0.8 TeV, the respective upper limits on σB(l* → lγ) are 0.75 and 0.90 fb for the e* and μ* searches. Limits on σB are converted into lower bounds on the compositeness scale Λ. In the special case where Λ = ml*, Excited-Electron and Excited-muon masses below 2.2 TeV are excluded.

Search for Excited Electrons in ppbar collisions at sqrt(s) = 1.96 TeV
Physical Review D, 2008Co-Authors: V.m. Abazov, B. Abbott, M. Abolins, B.s. Acharya, M. Adams, T. Adams, E. Aguilo, S.h. Ahn, M. Ahsan, G.d. AlexeevAbstract:We present the results of a search for the production of an Excited state of the Electron, e*, in proton-antiproton collisions at sqrt(s) = 1.96 TeV. The data were collected with the D0 experiment at the Fermilab Tevatron Collider and correspond to an integrated luminosity of approximately 1 fb^-1. We search for e* in the process ppbar -> e* e, with the e* subsequently decaying to an Electron plus photon. No excess above the standard model background is observed. Interpreting our data in the context of a model that describes e* production by four-fermion contact interactions and e* decay via electroweak processes, we set 95% C.L. upper limits on the production cross section ranging from 8.9 fb to 27 fb, depending on the mass of the Excited Electron. Choosing the scale for contact interactions to be Lambda = 1 TeV, Excited Electron masses below 756 GeV are excluded at the 95% C.L.
