Postdoctoral researcher position

Website ALBAsynchrotron Alba Synchrotron

ALBA is a 3rd generation synchrotron light source, serving Spanish, Portuguese, European, and world-wide users, who are part of a broad science and industrial community. Funded by the Spanish Government (Ministerio de Ciencia, Innovación y Universidades) and the Catalan Government (Generalitat de Catalunya, Departament d’Economia i Coneixement), we form a national user facility with well-established user programs, highly appreciated in the Spanish research context, and well embedded into the European research infrastructure landscape. Our highly motivated staff works in a multidisciplinary work environment with an atmosphere formed by lived diversity, inclusion and respect for our colleagues. Stationed at ALBA located close to Barcelona, you will find yourself in an area where others make vacation, with excellent connectivity to the world and an employer who understands the importance of life-work balance.

Under the Collaboration Framework Agreement and the Agreement establishing a Post-Doctoral joint program, signed between the Fundação para a Ciência e a Tecnologia (FCT) and the Consortium for the Construction, Equipment and Exploitation of the Synchrotron Light Laboratory (CELLS)we offer a postdoctoral researcher position working on the “Emergent magnetic and electronic properties of novel 2D layers and Moiré structures of Van-der-Waals Quantum Materials (2DMoireMagQMs” project and supporting the Portuguese 2D materials community.

Function

Description of the position

As a member of a research team formed by the groups of Profs. Joaquin Fernández-Rossier, Zhongchang Wang, Leonard Francis (International Iberian Nanotechnology Laboratory, Braga, Portugal (link)), Dr. Efrén Navarro (Instituto de Ciencia Molecular y Universidad de Valencia, Valencia, Spain (link)), Dr. Sergio O. Valenzuela (Catalan Institute of Nanoscience and Nanotechnology,  Spain (link)), and the Electronic and Magnetic Structure of Matter Section of ALBA (link), you will focus your scientific work on developing novel 2D layers and “Moiré” structures of magnetic Quantum Materials of Van-der-Waals type not realized or explored to date. You will be stationed in, and contracted by ALBA, but the collaboration will also require short term stays at the different laboratories of the collaboration partners.

Tasks

As the successful candidate, you will work with the 2DMoreMagQMs project consortium team towards developing novel 2D layers and “Moiré” structures of magnetic Quantum Materials of Van-der-Waals type, not realized or explored to date, in order to produce and investigate emergent electronic and magnetic states arising by the rupture of crystal symmetry and the frustration of electronic and magnetic orders characteristic of bulk forms. At the level of fabrication, top-down (cleaving, exfoliation) and bottom-up (evaporation, epitaxy) approaches will be used together with deterministic transfer in inert atmosphere (glove boxes) and/or clean room environments. The structural, electronic and magnetic properties of the systems will be investigated by complementary synchrotron radiation (ALBA), high-resolution transmission electron microscopy (INL and BIST) and laboratory techniques (ICN2, Univ. Valencia). More specifically, magnetic properties will be characterized using magneto-optical Kerr effect (MOKE) and x-ray magnetic circular dichroism (XMCD beamline at ALBA), with spatially resolved information provided via x-ray microscopy (PEEM endstation at ALBA); transport properties will be investigated by sheet resistance and Hall-type of measurements; electronic structure will be revealed via angle-resolved photo-emission spectroscopy (ARPES beamline at ALBA), while structural properties will be characterized by high resolution electron microscopy (SAED, Lorentz, EELS), x-ray diffraction and Raman-Photo-luminescence spectro-microscopy. The most relevant systems and results will be supported by theory calculations (INL).

You will develop your own scientific program aligned with the collaboration, groups, sections, and facilities goals and at the same time support users mostly, but not exclusively, aligned with your own scientific interests. In a diverse, highly interactive team, you will have excellent conditions to refine your scientific expertise, the technical and computational background, and most importantly build a broad and carrying network for your future scientific career. You will build national and international recognition by using opportunities to publish and present your scientific results and approaches at conferences, workshops and seminars.

Specifically, you will
•  Develop your own scientific program which will be strongly aligned with the scientific program of the collaboration team, the beamlines you will use, and in the larger context of the section and facility. In details this includes, developing the research plan, executing this plan with your research partners, contributing to the preparation of experimental proposals applying for general user beamtime at ALBA and/or other facilities, and contributing to the analysis and publication of the results.
•  Provide support to users from the field of 2D magnetic materials as Local Contact.
•  Participate on the maintenance, commissioning and upgrade activities of equipment used for this project.
•  Engage in the on-going beamline research program, national, Portuguese and European projects and collaborations. This may also include the initiation of new projects if appropriate.
•  Participate in the development of the ALBA II project, the upgrade project of ALBA to a 4th generation synchrotron.

Qualifications

REQUIREMENTS:

•    The applicant must have a doctorate in Chemistry, Physics or related disciplines.

•    The applicant must be Portuguese or have a permanent residence in Portugal.

•    Ability to propose, conduct, and contribute an independent research program using the instrumentation and expertise at the collaboration partners and ALBA.

•    A good level of English both written and spoken is a must. The working language at ALBA is English.

•    Good interpersonal skills and capabilities to work in a group, adaptability to a multidisciplinary environment, sense of responsibility and capabilities to work in a group as well as to work independently.

•    Ability to work within a multidisciplinary team.

SELECTION:

•    Considerable experimental background on magnetism.

•    Experience in the fabrication and characterization of 2D crystals and Van der Waals structures.

•    Experience in UHV and surface science techniques (LEED, MBE growth, etc).

•    Experience in exfoliation of bulk VdW single crystals onto large area flakes with thickenss down to a few atomic layers.

•    Experience with laboratory techniques such as Raman, Photo-luminescence or Magneto-optical Kerr effect applied to 2D materials.

•    Experience in synchrotron radiation techniques such as XMCD, ARPES, or XMCD-PEEM microscopy.

Other assets are:

•    A solid theoretical base, and some eventual experience running multiplet simulations and/or ab-initio methods.
