We employ a semiclassical multicarrier transport (MCT) model to analyze the magnetotransport of ZrTe5 nanodevices at hydrostatic pressures up to 2 GPa. The temperature dependence of the MCT results between 10 and 300 K is assessed in the context of thermal activation, and we obtain the positions of conduction and valence band edges in the vicinity of the chemical potential. We find evidence of the closing and subsequent re-opening of the band gap with increasing pressure, which is consistent with a phase transition from weak to strong TI. This matches expectations from ab initio band structure calculations, as well as previous observations that CVT-grown ZrTe5 is in a weak TI phase in ambient conditions.}, year = {2023}, orcid-numbers = {Kovács-Krausz, Zoltán/0000-0001-5821-6195; Oroszlány, László/0000-0001-5682-6424; Koltai, János/0000-0003-2576-9740; Nemes Incze, Péter/0000-0002-1222-3020; Tóvári, Endre/0000-0002-0000-3805} } @article{MTMT:33673970, title = {Revealing the band structure of ZrTe5 using multicarrier transport}, url = {https://m2.mtmt.hu/api/publication/33673970}, author = {Kovács-Krausz, Zoltán and Tóvári, Endre and Nagy, Dániel and Márffy, Albin Máté and Karpiak, Bogdan and Tajkov, Zoltán and Oroszlány, László and Koltai, János and Nemes Incze, Péter and Dash, Saroj P. and Makk, Péter and Csonka, Szabolcs}, doi = {10.1103/PhysRevB.107.075152}, journal-iso = {PHYS REV B}, journal = {PHYSICAL REVIEW B}, volume = {107}, unique-id = {33673970}, issn = {2469-9950}, year = {2023}, eissn = {2469-9969}, orcid-numbers = {Kovács-Krausz, Zoltán/0000-0001-5821-6195; Tóvári, Endre/0000-0002-0000-3805; Karpiak, Bogdan/0000-0001-7462-8405; Oroszlány, László/0000-0001-5682-6424; Koltai, János/0000-0003-2576-9740; Nemes Incze, Péter/0000-0002-1222-3020; Dash, Saroj P./0000-0001-7931-4843} } @article{MTMT:33226497, title = {The composition and structure of the ubiquitous hydrocarbon contamination on van der Waals materials}, url = {https://m2.mtmt.hu/api/publication/33226497}, author = {Pálinkás, András and Kálvin, György and Vancsó, Péter and Kandrai, Konrád and Szendrő, Márton and Németh, Gergely and Németh, Miklós and Pekker, Áron and Pap, József Sándor and Petrik, Péter and Kamarás, Katalin and Tapasztó, Levente and Nemes Incze, Péter}, doi = {10.1038/s41467-022-34641-7}, journal-iso = {NAT COMMUN}, journal = {NATURE COMMUNICATIONS}, volume = {13}, unique-id = {33226497}, issn = {2041-1723}, abstract = {The behavior of single layer van der Waals (vdW) materials is profoundly influenced by the immediate atomic environment at their surface, a prime example being the myriad of emergent properties in artificial heterostructures. 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} } @{MTMT:33111153, title = {Transport properties of TMDC materials}, url = {https://m2.mtmt.hu/api/publication/33111153}, author = {Márk, Géza István and Vancsó, Péter and Nemes Incze, Péter}, booktitle = {Eighth International Workshop Nanocarbon Photonics and Optoelectronics}, unique-id = {33111153}, year = {2022}, pages = {19-19}, orcid-numbers = {Vancsó, Péter/0000-0003-4333-9787; Nemes Incze, Péter/0000-0002-1222-3020} } @misc{MTMT:33111090, title = {Visible-frequency graphene plasmons}, url = {https://m2.mtmt.hu/api/publication/33111090}, author = {Dobrik, Gergely and Nemes Incze, Péter and Majérus, Bruno and Süle, Péter and Vancsó, Péter and Piszter, Gábor and Menyhárd, Miklós and Kalas, Benjamin and Petrik, Péter and Henrard, Luc and Tapasztó, Levente}, unique-id = {33111090}, year = {2022}, orcid-numbers = {Dobrik, Gergely/0000-0002-6690-274X; Nemes Incze, Péter/0000-0002-1222-3020; Vancsó, Péter/0000-0003-4333-9787; Piszter, Gábor/0000-0001-7155-4025; Menyhárd, Miklós/0000-0003-4581-5337; Petrik, Péter/0000-0002-5374-6952; Tapasztó, Levente/0000-0002-9377-8465} } @article{MTMT:33090541, title = {Observation of competing, correlated ground states in the flat band of rhombohedral graphite}, url = {https://m2.mtmt.hu/api/publication/33090541}, author = {Hagymási, Imre and Mohd, Isa M.S. and Tajkov, Zoltán and Márity, K. and Oroszlány, László and Koltai, János and Al-Assaf, Assem Mustafa Abd-Alrhman and Kun, Péter and Kandrai, Konrád and Pálinkás, András and Vancsó, Péter and Tapasztó, Levente and Nemes Incze, Péter}, doi = {10.1126/sciadv.abo6879}, journal-iso = {SCI ADV}, journal = {SCIENCE ADVANCES}, volume = {8}, unique-id = {33090541}, issn = {2375-2548}, year = {2022}, eissn = {2375-2548}, orcid-numbers = {Oroszlány, László/0000-0001-5682-6424; Koltai, János/0000-0003-2576-9740; Vancsó, Péter/0000-0003-4333-9787; Tapasztó, Levente/0000-0002-9377-8465; Nemes Incze, Péter/0000-0002-1222-3020} } @article{MTMT:33068873, title = {Revealing the topological phase diagram of ZrTe5 using the complex strain fields of microbubbles}, url = {https://m2.mtmt.hu/api/publication/33068873}, author = {Tajkov, Zoltán and Nagy, Dániel and Kandrai, Konrád and Koltai, János and Oroszlány, László and Süle, Péter and Horváth, Zsolt Endre and Vancsó, Péter and Tapasztó, Levente and Nemes Incze, Péter}, doi = {10.1038/s41524-022-00854-z}, journal-iso = {NPJ COMPUT MATER}, journal = {NPJ COMPUTATIONAL MATERIALS}, volume = {8}, unique-id = {33068873}, issn = {2057-3960}, abstract = {Topological materials host robust properties, unaffected by microscopic perturbations, owing to the global topological properties of the bulk electron system. Materials in which the topological invariant can be changed by easily tuning external parameters are especially sought after. Zirconium pentatelluride (ZrTe5) is one of a few experimentally available materials that reside close to the boundary of a topological phase transition, allowing the switching of its invariant by mechanical strain. Here, we unambiguously identify a topological insulator-metal transition as a function of strain, by a combination of ab initio calculations and direct measurements of the local charge density. Our model quantitatively describes the response to complex strain patterns found in bubbles of few layer ZrTe5 without fitting parameters, reproducing the mechanical deformation-dependent closing of the band gap observed using scanning tunneling microscopy. We calculate the topological phase diagram of ZrTe5 and identify the phase at equilibrium, enabling the design of device architectures, which exploit the topological switching characteristics of the system.}, year = {2022}, eissn = {2057-3960}, orcid-numbers = {Koltai, János/0000-0003-2576-9740; Oroszlány, László/0000-0001-5682-6424; Horváth, Zsolt Endre/0000-0002-4632-0136; Vancsó, Péter/0000-0003-4333-9787; Tapasztó, Levente/0000-0002-9377-8465; Nemes Incze, Péter/0000-0002-1222-3020} } @misc{MTMT:32816824, title = {Observation of visible-frequency graphene plasmons in nanocorrugated graphene}, url = {https://m2.mtmt.hu/api/publication/32816824}, author = {Tapasztó, Levente and Dobrik, Gergely and Nemes Incze, Péter and Majerus, Bruno and Süle, Péter and Vancsó, Péter and Henrard, Luc}, unique-id = {32816824}, year = {2022}, orcid-numbers = {Tapasztó, Levente/0000-0002-9377-8465; Dobrik, Gergely/0000-0002-6690-274X; Nemes Incze, Péter/0000-0002-1222-3020; Vancsó, Péter/0000-0003-4333-9787} } @article{MTMT:32100733, title = {Large-area nanoengineering of graphene corrugations hosting visible-frequency graphene plasmons}, url = {https://m2.mtmt.hu/api/publication/32100733}, author = {Dobrik, Gergely and Nemes Incze, Péter and Majerus, B and Süle, Péter and Vancsó, Péter and Piszter, Gábor and Menyhárd, Miklós and Kalas, Benjamin and Petrik, Péter and Henrard, L and Tapasztó, Levente}, doi = {10.1038/s41565-021-01007-x}, journal-iso = {NAT NANOTECHNOL}, journal = {NATURE NANOTECHNOLOGY}, volume = {17}, unique-id = {32100733}, issn = {1748-3387}, year = {2022}, eissn = {1748-3395}, pages = {61-66}, orcid-numbers = {Dobrik, Gergely/0000-0002-6690-274X; Nemes Incze, Péter/0000-0002-1222-3020; Vancsó, Péter/0000-0003-4333-9787; Piszter, Gábor/0000-0001-7155-4025; Menyhárd, Miklós/0000-0003-4581-5337; Petrik, Péter/0000-0002-5374-6952; Tapasztó, Levente/0000-0002-9377-8465} }
