Position scope: 

The main goal of the project is to use monolayers of semiconductor and dielectric materials to create a two-dimensional van der Waals junction (type III, the so-called 'broken gap') that will enable the construction of a tunneling transistor, in which the charge transport mechanism is based solely on the phenomenon of quantum tunneling. The key to creating a suitable two-dimensional junction is the selection of 2D materials such that their electron properties are mutually matched (appropriate mutual alignment of energy bands). Due to quantum phenomena, an important issue for the correct functioning of the nanodevice is the high purity of the interface of the junction. The technological challenge in the project will also be the fabrication of a device with nanocontacts and a top gate - all with dimensions of about 1-2 micrometers. The topics of the project combine competencies from the fields of materials engineering, physics and electronics. Prof. Mariusz Zdrojek will supervise the postdoc. 

What we require: 

• ability to start the post no later than on 1st January 2025, 

• Ph.D. in physics, materials science or related discipline,  

• at least 3 scientific articles published or accepted in a journal from the first quartile (Q1) of JCR (Journal Citation Report) list in the area of 2D materials fabrication and characterization, 

• Experimental experience in the area of 2D materials, especially in studying electrical properties of 2D materials and van der Waals heterostructures, 

• Experience in devices nanofabrication, clean-room and laboratory work, 

• Knowledge of research methods: Raman, AFM, SEM, PL, electrical measurements, 

• Knowledge of topics related to the fabrication of nanodevices based on 2D materials, 

• fluency in English that enables efficient communication, presentations during international conferences and writing scientific articles, 

What we offer: 

• 12-month full time employment at the best technical university in Poland with a strong possibility to extend it by the next 6-12 months after a positive evaluation, 

• ca. 8500 PLN net monthly enumeration (ca. 2000 EUR) [see information below about average costs of living in Warsaw] 

• public health insurance for the successful candidate and their family, 

• no obligatory teaching duties, 

• access to state-of-the-art equipment and fabrication facilities adapted to study production technology of 2D materials such as AFM (Bruker Icon), Raman spectrometer (Renishaw Qontor), e-beam lithography with SEM (Raith e-line plus), glove-box, plasma equipment, high-temperature vacuum furnace etc.     

• possibility to present research results at international conferences (funds for two international conferences per year), 

To apply, please send an email to mariusz.zdrojek(at)pw.edu.pl, asap but no later than 30 November 2024. The application should include: 

• a scanned copy of the candidate’s Ph.D. diploma, 

• a cover letter, explaining reasons for applying for this position, 

• a CV, 

• a list of publications and presentations at international conferences – please indicate your contribution in each of the papers, 

• names of at least two experts that could provide reference letters for the candidate 

Selected candidates will be invited for an online interview.  

Additional information about the costs of living in Warsaw: 

Warsaw is the capital of Poland, so in principle, it is one of the country's most expensive cities, but living in Warsaw is still much cheaper than in most European cities. In general, a single person in Warsaw can cover all necessary expenses (flat, media, transport, food) with ca. 5000-5500 PLN per month. The typical cost of renting a 2-room flat (30-40 square meters) varies between 2000-3000 PLN, depending on the part of the city. Electricity and media (TV, Internet) are usually not included in the rent and must be paid separately. The cost of lunch in the vicinity of the main campus of WUT is ca. 25-40 PLN, while a monthly ticket for public transport is 110 or 180 PLN depending on the area of validity. Public health insurance is included in the post (this includes also admission to hospitals); however, the medicines are paid separately.
