Job description

Offer DescriptionJob Summary:The winning candidate will work as a research assistant at the International Centre forInterfacing Magnetism and Superconductivity with Topological Matter – MagTop of theInstitute of Physics of the Polish Academy of Sciences. The Centre and the juniorpostdoctoral researcher position are supported by the MagTop project (FENG.02.01-IP.05-0028/23) implemented as part of the MAB FENG action of the Foundation forPolish Science co-financed by the European Union from the 2nd Priority funds of theProgramme European Funds for Smart Economy 2021-2027 (FENG).The job is related to the growth by molecular beam epitaxy (MBE) of optimized IV-VI/II-VI nanostructures for sensitive infrared detectors, as well as the growth ofnanostructures from an optimal material system to be found that would exhibit a robustquantum anomalous Hall effect. Optimization of structure design and growth technologyis to be carried out with artificial intelligence (AI) support.Job Description:Background: The quantum anomalous Hall effect (QAHE) is a relatively new quantumphenomenon first discovered in a special class of topological materials that aremagnetic. As well as being fascinating from a fundamental science point of view, itholds the promise of building a new type of resistance standard that, unlike standardsbased on the quantum Hall effect, will not require high magnetic fields to operate.Moreover, for this reason, in the future it can also be used in tandem with a voltagestandard based on the Josepshon effect to build new quantum kilogram and amperestandards.On the other hand, in today’s world, there is a huge demand for sensitive and fastdetectors operating in the mid- and long-wave region of the infrared spectrum, withapplications covering all areas of life, from industry to environmental protection tomedicine. A new class of very promising detectors of this type, proposed by MagTop, isbased on combining the advantages of two types of semiconductor compounds: II-VIand IV-VI, from which it is possible, using the MBE technique, to produce alternatelayers, each several atomic layers thick, the so-called superlattices (SL). Moreover,detectors of this type can potentially be cooled, in order to increase their sensitivity, bythermoelectric coolers made of the same compounds, integrated with them into amonolithic device.Aim: The aim of the project is to find the optimal material system and quantum structuredesign that would demonstrate robust QAHE and to design, fabricate and investigatedetector nanostructures based on II-VI/IV-VI superlattices. To this end, the most preciseInstitute of Physics of the Polish Academy of Sciencesand purest of all growth techniques, the molecular beam epitaxy (MBE) technique willbe used. The chosen researcher will work in a Lab equipped with VEECO’s world-class,multi-chamber MBE system. The optimization of structures design and growthparameters, in addition to the use of various characterization techniques (SEM, SQUID,XRD, AFM), will be supported by the use of artificial intelligence (AI)-based software.This software will be created and developed at MagTop with major participation of thejunior postdoctoral researcher, in parallel with the development of the QAHE anddetector nanostructures fabrication technology. The main research technique of QAHEwill be the low- and the ultra-low-temperature magnetotransport studies, involving theuse of a dilution refrigerator and a 3He-based system. The main research technique fordetector structures will be optical studies, involving the measurement of spectralsensitivity.Requirements:– A PhD degree in Physics or in related fields, such as e.g. materials engineering and

electronics held for no longer than five years, is required,– At least four years’ “hands on” experience in molecular beam epitaxial growth ofmaterials and quantum structures supported by publications is required,– Experience in using a GENxplor MBE system (from VEECO) will be an asset,– Experience in simulation of RHEED patterns will be an asset,– Experience in the MBE growth of IV-VI and II-VI nanostructures and topologicalmaterials will be an important asset,– At least four years’ experience in studies of materials with various experimentaltechniques (such as e.g. SEM, EDS, XRD) is required,– Experience in using various programming languages (especially Phyton, and e.g. C#,HTML, CSS, JavaScript, php, SQL) will be an asset,– Knowledge of machine learning (ML) algorithms for image analysis will be a greatasset,– Very good knowledge of written and spoken English is required.Main research field: PhysicsSub Research Field: Solid State Physics, NanotechnologyCareer Stage: Junior Postdoctoral Researcher – a person holding a doctoral degree for nolonger than five years.
