161 160 Principal Scientist Profiles Andrey Turchanin Andrey Turchanin Principal Scientist Profiles PROFESSOR OF PHYSICAL CHEMISTRY, FACULTY FOR CHEMISTRY AND EARTH SCIENCES Professor Andrey Turchanin received his Ph.D. in Solid State Physics (1999) from the National University of Science and Technology in Moscow. In 2000, he was awarded a Humboldt Research Fellowship at the University of Karlsruhe (now KIT). In 2010 he completed his habilitation on„Novel phenomena and materials in two-dimensional (2D) inorganic and organic systems“ at the University of Bielefeld. In 2012, Prof. Turchanin was awarded a Heisenberg Fellowship from the DFG, and in 2013 the Bernhard-Heß-Prize from the University of Regensburg for his research achievements in the field of emerging 2D materials. Since 2014, Prof. Turchanin is leading the Group of Applied Physical Chemistry and Molecular Nanotechnology at the Institute of Physical Chemistry of the Friedrich Schiller University Jena. In 2017, Prof. Turchanin was elected to the board of directors of the Center of Energy and Environmental Chemistry Jena (CEEC Jena); and since 2018 he is chairman of the Thuringia MiT-Group “2D Materials” and editor of the IOP “Journal of Physics: Materials”. ANDREY TURCHANIN RESEARCH AREAS Professor Turchanin’s research interests are focused on the following topics: • Tailored growth of 2D materials (e.g., graphene, TMDs) • Molecular self-assembly and molecular nanosheets • Electron irradiation induced materials synthesis • Stimuli-responsive surfaces and interfaces • Nanolithography and microfabrication • Nanoelectronic and nanophotonic devices • Chemical and biological sensors • Energy storage and energy conversion devices TEACHING FIELDS Professor Turchanin gives courses in: • Basic physical chemistry • Molecular nanotechnology and nanobiotechnology • Advanced characterization tools • Surface science • Nanolithography and microfabrication RESEARCH METHODS In the Turchanin’s lab as well as in collaboration with partners the following techniques and methods are employed: • Photoelectron and Auger spectroscopy (XPS/UPS, AES), Raman spectroscopy, polarisation modulation infrared reflection absorption spectroscopy (PM-IRRAS), second harmonic generation (SHG), surface plasmon resonance (SPR) measurements • Scanning probe microscopy (STM/AFM), scanning/ transmission electron microscopy (SEM/TEM), helium ion microscopy (HIM), optical microscopy • Low energy electron diffraction (LEED) • Extreme UV interference lithography (EUV-IL), electron beam lithography (EBL), photolithography • Electric and optoelectronic transport measurements ADVANCED CHEMICAL VAPOR DEPOSITION (CVD) GROWTH OF TRANSITION METAL DICHALCOGENIDE MONOLAYERS (TMDS) FOR STUDYING NOVEL ELECTRONIC AND PHOTONIC PHENOMENA, AND APPLICATIONS Turchanin’s group has recently developed an advanced method for the CVD growth from solid state precursors of large area TMD monolayers (e.g., MoS2, WS2, MoSe2, WSe2, etc.) on various substrates such as SiO2/Si and sapphire wafers [11], Figure 2a-d. The resulting CVD grown monolayers possess high structural, optical and electronic properties which are comparable to the monolayers obtained by mechanical exfoliation of the TMD bulk crystals [12]. The development methodology significantly facilitates implementation of TMD monolayers in studies of novel physical phenomena, such as, e.g., properties of the interlayer excitons in van der Waals heterostructures of 2D materials (see Figure 2e-g) [8], engineering of novel photonic metasurfaces [13], non-linear optical elements [10, 14], field-effect transistors [11, 15] and functional nanostructures [14, 16]. RECENT RESEARCH RESULTS Andrey Turchanin’s current research activities are focused on 2D materials (graphene, transition metal dichalcogenides, molecular nanomembranes, organic monolayers) and their hybrids with other low-dimensional materials for basic studies and novel applications in nanoelectronics, nanophotonics, nanobiotechnology, sensors as well as energy storage/ conversion, see Figure 1. These interdisciplinary activities embrace (i) tailored materials synthesis [1-2], (ii) in depth characterization by spectroscopy and microscopy methods down to the nanoscale [3-4], (iii) nanolithography and microfabrication [5-6], (iv) studying of fundamental electronic, optic and optoelectronic properties [7-8], (v) implementation of 2D materials in devices, stimuliresponsive surfaces and interfaces [9-10].
