Impact of dopant species on the interfacial trap density and mobility in amorphous In-X-Zn-O solution-processed thin-film transistors
Mohammed Benwadih, J. A. Chroboczek, Gerard Ghibaudo +2
Alloying of In/Zn oxides with various X atoms stabilizes the IXZO structures but generates electron traps in the compounds, degrading the electron mobility. To assess whether the l…
Real-space perturbation theory for frustrated magnets: application to magnetization plateaus
M. E. Zhitomirsky
We present a unified approach to the problem of degeneracy lifting in geometrically frustrated magnets with and without an external field. The method treats fluctuations around a c…
Spin excitations in the two-dimensional strongly coupled dimer system malachite
E. Canevet, B. Fak, R. K. Kremer +7
The mineral malachite, Cu2(OD)2CO3, has a quantum spin-liquid ground state and no long-range magnetic order down to at least T=0.4 K. Inelastic neutron scattering measurements show…
Raman-assisted crystallography reveals end-on peroxide intermediates in a nonheme iron enzyme
Gergely Katona, Philippe Carpentier, Vincent Nivière +5
Iron-peroxide intermediates are central in the reaction cycle of many iron-containing biomolecules. We trapped iron(III)-(hydro)peroxo species in crystals of superoxide reductase (…
Reaction of the desulfoferrodoxin from Desulfoarculus baarsii with superoxide anion. Evidence for a superoxide reductase activity
M Lombard, M Fontecave, D Touati +1
Desulfoferrodoxin is a small protein found in sulfate-reducing bacteria that contains two independent mononuclear iron centers, one ferric and one ferrous. Expression of desulfofer…
M{ö}ssbauer characterization of an unusual high-spin side-on peroxo-Fe3+ species in the active site of superoxide reductase from Desulfoarculus Baarsii. Density functional calculations on related models
Olivier Horner, Jean-Marie Mouesca, Jean-Louis Oddou +9
Superoxide reductase (SOR) is an Fe protein that catalyzes the reduction of superoxide to give H(2)O(2). Recently, the mutation of the Glu47 residue into alanine (E47A) in the acti…
