Nanocrystalline superconducting γ-Mo2N ultra-thin films for single photon detectors

Autor: J.A. Hofer, Nestor Fabian Haberkorn, S. Bengió, M. Ginzburg

Publikováno v: Materials Science and Engineering: B. 275:115499

We analyze the influence of the surface passivation produced by oxides on the superconducting properties of γ-Mo2N ultra-thin films. The superconducting critical temperature of thin films grown directly on Si (100) with those using a buffer and a ca

Selective activation of memristive interfaces in TaO

Autor: C, Ferreyra, M J, Sánchez, M, Aguirre, C, Acha, S, Bengió, J, Lecourt, U, Lüders, D, Rubi

Publikováno v: Nanotechnology. 31(15)

The development of novel devices for neuromorphic computing and non-traditional logic operations largely relies on the fabrication of well controlled memristive systems with functionalities beyond standard bipolar behavior and digital ON-OFF states.

The martensitic transformation of polycrystalline thin films based on shape memory alloys is usually affected by the average grain size and by the thickness. We have carried out a study of the temperature driven martensitic transformation in micromet

We report on the influence of the disorder and stoichiometry in the resulting superconducting critical temperature of γ-Mo2N thin films. Initially, three films (with Tc values of 7.6 K, 6.8 K and 6 K) were grown at room temperature by reactive sputt

Tuning the magneto-electrical properties of multiferroic multilayers through interface strain and disorder

Autor: M. Granada, Alberto Leyva, L. Neñer, Pablo Granell, S. Soria, N. Haberkorn, Federico Golmar, Martin Sirena, J. Gonzalez Sutter, A. Sarmiento Chávez, S. Bengió

Publikováno v: Journal of Alloys and Compounds. 859:157820

Artificially engineered superlattices were designed and fabricated to induce different growth mechanisms and structural characteristics. DC sputtering was used to grow ferromagnetic (La0.8Ba0.2MnO3)/ferroelectric (Ba0.25Sr0.75TiO3 or BaTiO3) superlat
