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:34004074, title = {Phonon-Assisted Tunneling through Quantum Dot Systems Connected to Majorana Bound States}, url = {https://m2.mtmt.hu/api/publication/34004074}, author = {Máthé, L. and Kovács-Krausz, Zoltán and Botiz, I. and Grosu, I. and El, Anouz K. and El, Allati A. and Zârbo, L.P.}, doi = {10.3390/nano13101616}, journal-iso = {NANOMATERIALS-BASEL}, journal = {NANOMATERIALS}, volume = {13}, unique-id = {34004074}, year = {2023}, eissn = {2079-4991}, orcid-numbers = {Kovács-Krausz, Zoltán/0000-0001-5821-6195} } @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:32130144, title = {New method of transport measurements on van der Waals heterostructures under pressure}, url = {https://m2.mtmt.hu/api/publication/32130144}, author = {Fülöp, Bálint and Márffy, Albin Máté and Tóvári, Endre and Kedves, Máté and Zihlmann, Simon and Indolese, David and Kovács-Krausz, Zoltán and Watanabe, Kenji and Taniguchi, Takashi and Schönenberger, Christian and Kézsmárki, István and Makk, Péter and Csonka, Szabolcs}, doi = {10.1063/5.0058583}, journal-iso = {J APPL PHYS}, journal = {JOURNAL OF APPLIED PHYSICS}, volume = {130}, unique-id = {32130144}, issn = {0021-8979}, year = {2021}, eissn = {1089-7550}, orcid-numbers = {Fülöp, Bálint/0000-0001-6853-2642; Márffy, Albin Máté/0000-0002-5652-460X; Tóvári, Endre/0000-0002-0000-3805; Kedves, Máté/0000-0002-2057-4891; Zihlmann, Simon/0000-0001-5717-2063; Indolese, David/0000-0002-9436-8994; Kovács-Krausz, Zoltán/0000-0001-5821-6195; Watanabe, Kenji/0000-0003-3701-8119; Taniguchi, Takashi/0000-0002-1467-3105; Kézsmárki, István/0000-0003-4706-3247; Makk, Péter/0000-0001-7637-4672; Csonka, Szabolcs/0000-0003-0505-2806} } @article{MTMT:31357113, title = {Electrically Controlled Spin Injection from Giant Rashba Spin–Orbit Conductor BiTeBr}, url = {https://m2.mtmt.hu/api/publication/31357113}, author = {Kovács-Krausz, Zoltán and Hoque, Anamul Md and Makk, Péter and Szentpéteri, Bálint and Kocsis, Mátyás and Fülöp, Bálint and Yakushev, Michael Vasilievich and Kuznetsova, Tatyana Vladimirovna and Tereshchenko, Oleg Evgenevich and Kokh, Konstantin Aleksandrovich and Lukács, István Endre and Taniguchi, Takashi and Watanabe, Kenji and Dash, Saroj Prasad and Csonka, Szabolcs}, doi = {10.1021/acs.nanolett.0c00458}, journal-iso = {NANO LETT}, journal = {NANO LETTERS}, volume = {20}, unique-id = {31357113}, issn = {1530-6984}, year = {2020}, eissn = {1530-6992}, pages = {4782-4791}, orcid-numbers = {Kovács-Krausz, Zoltán/0000-0001-5821-6195; Fülöp, Bálint/0000-0001-6853-2642; Lukács, István Endre/0000-0002-4985-4475} } @article{MTMT:3148115, title = {Gate-controlled conductance enhancement from quantum Hall channels along graphene p-n junctions}, url = {https://m2.mtmt.hu/api/publication/3148115}, author = {Tóvári, Endre and Makk, Péter and Liu, Ming-Hao and Rickhaus, Peter and Kovács-Krausz, Zoltán and Richter, Klaus and Schönenberger, Christian and Csonka, Szabolcs}, doi = {10.1039/C6NR05100F}, journal-iso = {NANOSCALE}, journal = {NANOSCALE}, volume = {8}, unique-id = {3148115}, issn = {2040-3364}, year = {2016}, eissn = {2040-3372}, pages = {19910-19916}, orcid-numbers = {Tóvári, Endre/0000-0002-0000-3805; Kovács-Krausz, Zoltán/0000-0001-5821-6195} }
