20.500.12556/RUL-187747 Električno krmiljenje metastabilnih stanj v 1\textit{T}-TaS$_2$ in EuTe$_4$ Electrical Manipulation of Metastable States in 1\textit{T}-TaS$_2$ and EuTe$_4$ Metastabilna stanja so stanja, ki so stabilna (na določeni časovni skali), vendar ne predstavljajo globalnega energijskega minimuma sistema. Leta 2014 je bil prvič izveden kontroliran preklop v elektronsko metastabilno stanje v 1\textit{T}-TaS$_2$, kar je odprlo vrata do preučevanja nove fizike in predstavilo pot do aplikativne uporabe. V tej magistrski nalogi bom predstavil kontrolo metastabilnih elektronskih stanj v materialih 1\textit{T}-TaS$_2$ in EuTe$_4$. V prvem delu naloge bom preučil vpliv substrata iz aluminija 7075 na temperaturno stabilnost metastabilnega stanja 1\textit{T}-TaS$_2$ in pokazal stabilnost pri višji temperaturi, kot doseženo s standardnimi substrati. V drugem delu naloge bom predstavil meritve na novem materialu EuTe$_4$, kjer pokažem nadzorovan preklop v dolgoživo metastabilno elektronsko stanje pri sobni temperaturi! Metastable states are states that are stable (on a certain time scale) but do not represent the global energy minimum of the system. In 2014, the first controlled transition to an electronic metastable state was achieved in 1\textit{T}-TaS$_2$, which opened the door to the study of new physics and presented a path to practical applications. In this master’s thesis, I will present the control of metastable electronic states in the materials 1\textit{T}-TaS$_2$ and EuTe$_4$. In the first part of the thesis, I will examine the effect of an aluminum 7075 substrate on the temperature stability of the metastable state in 1\textit{T}-TaS$_2$ and demonstrate stability at a higher temperature than that achieved with standard substrates. In the second part of the thesis, I will present measurements on the new material EuTe$_4$, where I will demonstrate a controlled transition to a long-lived metastable electronic state at room temperature! metastabilno stanje val gostote naboja 1\textit{T}-TaS$_2$ EuTe$_4$ skrito stanje električni preklop moiré-jeva super-struktura metastable state charge density wave 1\textit{T}-TaS$_2$ EuTe$_4$ hidden state electrical switch moiré super-structure true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2026-09-13 08:15:37 2026-09-13 08:15:40 2026-09-14 04:29:01 0000-00-00 00:00:00 2026 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 163713 23897.pdf 23897.pdf 1 D3FD25E6AB304BC0DF2C89FD424FF6AB 21ef38b3d1a1326fefe44f59e6257a08d9e541faef5561f01bfba5af9dd4de7b 840808cf-af3a-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=247489 Fakulteta za matematiko in fiziko 0 0 0
