Equally significant are adsorbates deposited onto their surface from ambient. While vdW interfaces are well understood, our knowledge regarding atmospheric contamination is severely limited. Here we show that the common ambient contamination on the surface of: graphene, graphite, hBN and MoS2 is composed of a self-organized molecular layer, which forms during a few days of ambient exposure. Using low-temperature STM measurements we image the atomic structure of this adlayer and in combination with infrared spectroscopy identify the contaminant molecules as normal alkanes with lengths of 20-26 carbon atoms. Through its ability to self-organize, the alkane layer displaces the manifold other airborne contaminant species, capping the surface of vdW materials and possibly dominating their interaction with the environment.}, year = {2022}, eissn = {2041-1723}, orcid-numbers = {Vancsó, Péter/0000-0003-4333-9787; Petrik, Péter/0000-0002-5374-6952; Kamarás, Katalin/0000-0002-0390-3331; Tapasztó, Levente/0000-0002-9377-8465; Nemes Incze, Péter/0000-0002-1222-3020} } @article{MTMT:33200914, title = {Molecular Encapsulation from the Liquid Phase and Graphene Nanoribbon Growth in Carbon Nanotubes}, url = {https://m2.mtmt.hu/api/publication/33200914}, author = {Cadena Nogales, Ana Cristina and Botka, Bea and Pekker, Áron and Tschannen, CD and Lombardo, C and Novotny, L and Khlobystov, AN and Kamarás, Katalin}, doi = {10.1021/acs.jpclett.2c02046}, journal-iso = {J PHYS CHEM LETT}, journal = {JOURNAL OF PHYSICAL CHEMISTRY LETTERS}, volume = {13}, unique-id = {33200914}, issn = {1948-7185}, year = {2022}, pages = {9752-9758}, orcid-numbers = {Botka, Bea/0000-0003-3707-3097; Kamarás, Katalin/0000-0002-0390-3331} } @article{MTMT:33168634, title = {Evaluation of surface passivating solvents for single and mixed halide perovskites}, url = {https://m2.mtmt.hu/api/publication/33168634}, author = {Özeren, Mehmet Derya and Pekker, Áron and Kamarás, Katalin and Botka, Bea}, doi = {10.1039/d2ra04278a}, journal-iso = {RSC ADV}, journal = {RSC ADVANCES}, volume = {12}, unique-id = {33168634}, issn = {2046-2069}, abstract = {Surface passivation is one of the commonly used approaches to reduce the density of defects on the surfaces and interfaces hindering the performance and stability of perovskite optoelectronic devices. Although surface passivation leads to performance improvement for the targeted devices, details of the complex intermolecular interactions occurring between the molecules and perovskites are not entirely known. Here, we investigated a variety of commonly used solvents in the post-processing of perovskites by using photoluminescence (PL) spectroscopy on single and mixed halide perovskites (MAPbI(3), MAPbBr(3) and MAPb(Br0.5I0.5)(3)). Our results show that solvents with medium and low Gutmann donor and acceptor numbers provide PL intensity increase for both single halide perovskites by passivating the surface defect sites. Among the single halide perovskites, MAPbBr(3) is more attracted to hydrogen bonding solvents, in contrast to MAPbI(3) that is preferred by Lewis bases. This halide selective attraction also has an influence on the mixed-halide composition. Identifying these interaction mechanisms provides new insights into passivating the surface of perovskites for future device design.}, keywords = {TEMPERATURE; EFFICIENCY; SEGREGATION; coordination; SOLAR-CELL}, year = {2022}, eissn = {2046-2069}, pages = {28853-28861}, orcid-numbers = {Özeren, Mehmet Derya/0000-0001-7049-9183; Kamarás, Katalin/0000-0002-0390-3331; Botka, Bea/0000-0003-3707-3097} } @article{MTMT:32785441, title = {Direct Visualization of Ultrastrong Coupling between Luttinger-Liquid Plasmons and Phonon Polaritons}, url = {https://m2.mtmt.hu/api/publication/32785441}, author = {Németh, Gergely and Otsuka, K. and Datz, Dániel and Pekker, Áron and Maruyama, S. and Borondics, F. and Kamarás, Katalin}, doi = {10.1021/acs.nanolett.1c04807}, journal-iso = {NANO LETT}, journal = {NANO LETTERS}, volume = {22}, unique-id = {32785441}, issn = {1530-6984}, year = {2022}, eissn = {1530-6992}, pages = {3495-3502}, orcid-numbers = {Kamarás, Katalin/0000-0002-0390-3331} } @article{MTMT:32456617, title = {Structure investigation and vibrational spectroscopy of two prospective hybrid perovskites based on Mn and Co}, url = {https://m2.mtmt.hu/api/publication/32456617}, author = {Abdel-Aal, S.K. and Bortel, Gábor and Pekker, Áron and Kamarás, Katalin and Faigel, Gyula and Abdel-Rahman, A.S.}, doi = {10.1016/j.jpcs.2021.110400}, journal-iso = {J PHYS CHEM SOLIDS}, journal = {JOURNAL OF PHYSICS AND CHEMISTRY OF SOLIDS}, volume = {161}, unique-id = {32456617}, issn = {0022-3697}, year = {2022}, eissn = {1879-2553}, orcid-numbers = {Kamarás, Katalin/0000-0002-0390-3331} } @article{MTMT:34038583, title = {Fascinating structure and physical properties of lead-free hybrid perovskites for multifunctional applications}, url = {https://m2.mtmt.hu/api/publication/34038583}, author = {Abdel-Aal, SK and Abdel-Rahman, AS and Bortel, Gábor and Pekker, Áron and Kamarás, Katalin and Faigel, Gyula}, journal-iso = {ACTA CRYSTALLOGR A FOUND ADV}, journal = {ACTA CRYSTALLOGRAPHICA SECTION A: FOUNDATIONS AND ADVANCES}, volume = {77}, unique-id = {34038583}, issn = {2053-2733}, year = {2021}, eissn = {2053-2733}, pages = {C754-C754}, orcid-numbers = {Kamarás, Katalin/0000-0002-0390-3331} } @article{MTMT:32765949, title = {Vibrational spectroscopy as a confirmation method for structural analysis}, url = {https://m2.mtmt.hu/api/publication/32765949}, author = {Abdel-Rahman, AS and Abdel-Aal, SK and Faigel, Gyula and Kamarás, Katalin and Bortel, Gábor and Pekker, Áron}, journal-iso = {ACTA CRYSTALLOGR A FOUND ADV}, journal = {ACTA CRYSTALLOGRAPHICA SECTION A: FOUNDATIONS AND ADVANCES}, volume = {77}, unique-id = {32765949}, issn = {2053-2733}, year = {2021}, eissn = {2053-2733}, pages = {C956-C956}, orcid-numbers = {Kamarás, Katalin/0000-0002-0390-3331} }
