Fotoinducirana koherentna teraherčna emisijska spektroskopija v stanju z valom gostote naboja, Magistrska naloga

Mentor: doc. dr. Tomaž Mertelj (tomaz.mertelj@ijs.si) Snovi z valom elektronske gostote so postale ena od pomembnejših tem v neravnovesni fiziki trdne snovi. Pri tem zaradi razpoložljivosti laserjev s femtosekundnimi svetlobnimi bliski in enostavnosti prevladujejo optične metode, kjer s stroboskopskimi metodami merimo ultrahitre spremembe dielektrične funkcije v širokem spektralnem področju. Pri tem navadno merimo optično prepustnost […]

Time-resolved reflectivity and Raman studies of the interplay of electronic orders in Mo8 O23

Molybdenum suboxides have been gaining attention lately due to their potential as charge storage materials and memory elements. In spite of increased interest in their functional properties, the phase diagrams, transient, and even equilibrium optical properties have not been systematically studied for many molybdenum suboxides, such as, for example, monoclinic semimetallic Mo8O23. This compound undergoes an […]

Mottness collapse without metallization in the domain wall of the triangular-lattice Mott insulator 1T−TaS2

Domain walls in insulating materials may be orders of magnitude more conducting than the bulk, allowing one to design the material functionality by their patterning. Studies of inhomogeneities such as domain walls in the presence of strong electronic interactions is a very challenging problem. A particularly interesting case is that of Mott insulators, where electrons are […]
