Molecular Beam Epitaxy (MBE) Scientist/Engineer (ICN2)

Description of Group/Project:

The PEN group led by ICREA Prof. Sergio O. Valenzuela counts with about 10 members, including senior researchers, postdoctoral fellows, and PhD students. The group carries out both basic research and nanomaterial engineering for electronic nanodevices applications. Current focus is on spin physics in two-dimensional materials, including graphene, TMDCs and TIs, thermoelectricity and quantum information. For more information on the institute and PEN group activities and recent publications, refer to and The PEN MBE cluster comprises two growth chambers and an XPS/Auger/sample prep system. The first growth chamber, which is equipped with RHEED, is dedicated to TIs and TMDCs, the second chamber, with tilting stage, is dedicated to insulating materials (MgO, EuS), and metals (Al, Ag, NiFe, Co,…). The cluster has a docking port for a UHV suitcase to transfer films to/from the ALBA synchrotron (1km away) and other in-house equipment (XPS, LEED, STM, ARPES, pulsed laser deposition cluster).

The appointed candidate will be responsible for performing epitaxial growth and characterization of semiconducting compounds and heterostructures. The compounds include topological insulators (TI) of the (Bi,Sb)2(Se,Te)3 family of materials and transition metal dichalcogenides (TMDC). S/he will carry out process development, documentation of processes and implement the necessary maintenance of growth-lab and ancillary equipment. S/he will interface with the other PEN members, focused on (electronic) devices that use the grown heterostructures, and with Laboratory Engineers that are in charge of the common facilities at the ICN2. The latter include x-ray diffraction (XRD), x-ray photoelectron spectroscopy (XPS), angle-resolved photoemission spectroscopy (ARPES), and scanning and transmission electron microscopy.

The position will be funded by a European FET-Proactive project coordinated by Prof. Sergio O. Valenzuela, leader of the PEN group. The appointment is initially for a period of 2 years with a possibility of extension.

Postdoctoral Researcher (ICN2)

Description of Group/Project:

The P2N research topics include studies based on phonon and phot on confinement, optomechanics, nanoscale heat transport and phononic and photonic crystals in semiconductor, organic and oxide nanostructures. The group carries out pioneering in nanophononics and in nanofabrication and nanometrology.

The position is connected to an EU-FET project in on Topological bosonics starting in January 2019 to develop the next generation of topological devices and architectures across which information can flow without losses. This conceptually simple yet technologically and fundamentally challenging requirement is crucial for the development of technologies in fields ranging from information processing to quantum communication and metrology. In each of these areas, the dissipation of information is a key hurdle that leads, for example, to unacceptable thermal loads or error rates. This project will harness topological protection in novel materials and nanoscopic structures to empower electrons, phonons and photons to flow with little or no dissipation and, ultimately, crosslink them within a hybrid platform. This will entail the design of novel topological photonic/phononic waveguides and the engineering of disruptive heterostructures elaborated from the combination of topological insulators and ferromagnetic materials. In the optical domain, this will enable the creation of reflection and scattering free waveguides and, in thermal management, efficient transport and localized dissipation of heat. The project aims gathering a young consortium and fosters the creation of a new community in Europe on the use of topology for Information and Communication Technologies (ICT). Thanks to its high interdisciplinary embodiment involving electronic materials, optics, thermal management and metrology, the project will help advance all levels of the value chain, from fundamental science to engineering and technology.

Main Tasks and responsibilities:

The candidate will conduct analytical theory combined with simulations using group theory to specifically design and optimization of topological waveguides for bosons. In particular, the candidate will explore and optimize novel and existing designs for planar and layered topological waveguides and heterostructures for near-infrared photons and phonons in a wide spectral range from few to 100’s of GHz. Based on topological photonic crystals, these waveguides will be optimized for low-loss transport while simultaneously controlling the dispersion and topology of photonic and phononic modes.

The ALBA Synchrotron and the Instituto de Química Física “Rocasolano” (CSIC) are looking for a PhD candidate

for the joint research project "A real space study of functional oxide growth on metal substrates"

Transition metal (TM) oxides are a family of materials with a wide range of physical properties and rich phase diagrams. The ability to grow high quality oxide thin films and heterostructures combined with the versatility of oxide properties opens the path to a large number of applications in oxide electronics such as field effect transistors (FETs) or spintronics. Oxides are also widely used as catalysts or catalyst constituents. Controlling the growth of oxides, especially of low dimensionality, is both a challenge and a promising path to the discovery of new physical phenomena and their application in novel technologies. The present PhD project addresses the in-situ growth of low dimensional TM oxide structures on metal substrates, and their characterization with special emphasis on surface and interface effects. For this end we will exploit the unique capabilities of Low Energy Electron Microscopy (LEEM) for in-situ observation of reactive molecular beam epitaxy, and the possibility of performing surface structural, chemical and magnetic characterization at the nanoscale in the same instrument by X-Ray PhotoEmission Electron Microscopy (XPEEM). The project is a collaboration of the ALBA Synchrotron and the Instituto de Química Física “Rocasolano” (IQFR), leading Spanish groups in LEEM/XPEEM. It will combine the use of the LEEM/XPEEM station of the CIRCE beamline at the ALBA Synchrotron (Barcelona) with complementary measurements and data analysis at the IQFR laboratory (Madrid) using X-ray Photoelectron Spectroscopy, Low Energy Electron Diffraction, Scanning Tunneling Microscopy, and Mössbauer spectroscopy.

The project will take place at the ALBA Synchrotron in Barcelona and the Instituto de Química Física “Rocasolano” in Madrid. The Alba Synchrotron ( is the largest Spanish scientific facility, with a lively international scientific working environment. The IQFR institute ( is part of a cluster of research institutes at the CSIC campus of Serrano close to the city center. The recipient will share his/her time between both sites. Candidates should have a degree in Physics, Chemistry or a related discipline and be in a position to join a PhD program in Spain. We are looking for highly motivated individuals with an interest in materials and surface science. Experience with synchrotron studies, vacuum equipment, and programming skills are an advantage. Curiosity and motivation for groundbreaking science is assumed. The appointment will be for a maximum of four years.

Interested candidates should send their CV and application letter to Dr. Juan de la Figuera (This email address is being protected from spambots. You need JavaScript enabled to view it.) and Dr. Lucía Aballe (This email address is being protected from spambots. You need JavaScript enabled to view it.).
