CONVOCATORIA DEL MES DE SEPTIEMBRE 2022 DE OFERTA DE CONTRATO OTT-UPM PARA INVESTIGACIÓN, POSTGRADUADO NO DOCTOR / PHD STUDENT RESEARCHER. FIRST STAGE RESEARCHER (R1).

Investigación sobre la fabricación y caracterización de fuentes de fotones individuales basadas en GaN. Esto incluye el crecimiento epitaxial de la estructura mediante epitaxia de haces moleculares y la consiguiente caracterización morfológica, estructural y óptica mediante diferentes técnicas experimentales. Las fuentes de fotones individuales deben tener una longitud de onda de emisión sintonizable, una vida útil de emisión y, preferiblemente, poder operar a temperatura ambiente.

Research on the fabrication and characterization of GaN based single photon sources. This includes epitaxial growth of the structure by molecular beam epitaxy and consequent morphological, structural and optical characterization by different experimental techniques. The single photon sources should have tunable emission wavelength, emission lifetime and, preferentially, be able to operate at room temperature.

CONVOCATORIA DEL MES DE SEPTIEMBRE 2022 DE OFERTA DE CONTRATO OTT-UPM PARA INVESTIGACIÓN, QUANTUM KEY DISTRIBUTION ENGINEER ESTABLISHED RESEARCHER (R3).

The first goal of the project is instalation of a quantum key distribution system, based on phase-codified Max-Zender interferometer. The final goal of the project is design and installation of the first quantum network capable of connecting entire Europe. The work will focus on the assembly of an experimental quantum key distribution system and its integration into the global optical fiber network. The research will be carried out at the Institute for Optoelectronic Systems and Microtechnology (www.isom.upm.es), at the faculty ETSI Telecommunicación, in a close collaboration with the research group on Information and Quantum Computing (GIICC) at the faculty ETSIInformática, both faculties at Universidad Politécnica de Madrid.

Abstract

Multi-segmented cylindrical nanowires (NWs) are the most promising systems for 3D racetrack memory devices, where information is stored as in-line magnetic domains. However, reading and writing information is still a challenge, as external reading/writing heads have to be implemented near the tracks. The writing component should be made of a bilayered soft/hard coupled magnetic system, so that information could be easily written by external magnetic fields. Here, we demonstrate the feasibility of using a Ni90Cu10/Fe20Co80 segmented NW as the writing element, in which magnetic information is written by applying external magnetic fields. Using low-cost template-assisted electrodeposition methods, single, bi- and multi-segmented NW hexagonal arrays of NiCu and FeCo/Au were fabricated. A throughout magnetic characterization using magnetic hysteresis loops, ferromagnetic resonance and first-order reversal curves (FORCs) revealed that the soft segment (NiCu) induced the reversal of the hard segment (FeCo) in a two-step process, reducing its coercive and effective anisotropy fields when coupled. Finally, micromagnetic simulations certified the experimental observations of a multi-step reversal process. This work demonstrates the important role of interface interactions for the future implementation of an in-line writing component in a 3D racetrack memory device, enhancing their potential applicability.

Abstract

We present results from extensive Monte Carlo simulations on the crystallization of athermal polymers under full confinement. Polymers are represented as freely jointed chains of tangent hard spheres of uniform size. Confinement is applied through the presence of flat, parallel, and impenetrable walls in all dimensions. We analyze crystallization as the summation of two contributions: one that occurs in the bulk volume of the system (bulk crystallization), and one on the wall surfaces (surface crystallization). Depending on volume fraction initially amorphous (disordered) hard-sphere chain packings transit to the stable crystal phase. The established ordered morphologies consist primarily of hexagonal close-packed (HCP) crystals in the bulk volume and of triangular (TRI) crystals on the surface. As in the case of athermal packings in the bulk (without confinement), a structural competition is observed between the 5-fold local symmetry and the formation of close-packed crystallites. Effectively, the full confinement inside a cube favors the growth of the HCP crystal, as the FCC one is quite incompatible with the imposed spatial constraints. Consequently, we observe the formation of noncompact ordered motifs which grow from the surface to the inner volume of the simulation cell. We further compare the 2D and 3D crystals formed by monomeric hard spheres under the same simulation conditions. Significant differences are observed at low densities that tend to diminish as concentration increases.
