dc.description.abstract In this paper, we report a number of atypical features of superconductivity, weak ferromagnetism, and quantum transport observed at low temperatures at bicrystalline interfaces of the first predicted and experimentally realized three-dimensional topological insulator (3D TI) Bi1-xSbx (0 ≤ x ≤ 0.2). Pure bicrystals and bicrystals slightly doped (≤0.01 at %) with Te (donor) and Sn (acceptor) impurities are used to fully satisfy the conditions of manifestation of transport quantum oscillations. These 3D TI interfaces exhibit fascinating quantum topological properties, which require extensive basic and applied research. en_US
dc.description.abstract In presentul articol raportăm o serie de caracteristici atipice ale supraconductibilităţii, feromagnetismului slab și transportului cuantic observate la temperature joase la interfețele bicristaline ale primului izolator topologic tridimensional (3D TI), prezis și realizat experimental in aliajele Bi1-xSbx (0 ≤ x ≤ 0.2). Bicristale pure și ușor dopate (≤0.01 at. %) cu impurități deTe (donor) și Sn (acceptor) au fost utilizate pentru a satisface pe deplin condițiile de manifestare a oscilațiilor cuantice de transport. Aceste interfețe 3D TI manifestă proprietăți topologice cuantice fascinante, care necesită cercetări fundamentale și applicate extinse. en_US
