Sažetak
Good understanding of how properties can be tuned by changing the size of material is the basic prerequisite for the production of new materials with designed superior properties. Systems with charge density wave (CDW) as a type of coupled electronic-lattice instability (usually found in low dimensional materials) are especially interesting due to their exceptional properties such as giant dielectric constant, nonlinear transport, memory effects, unusual electro-mechanical and thermoelectric properties, all of conceptual importance in various thin film applications. On the other hand, CDW films open the door for studying of meso- and micro-scale aspects of CDW physics caused by finite size effects. Here we present widely covered investigation of thin granular films of CDW prototype system K0.3MoO3 (blue bronze) prepared by pulsed laser deposition and characterized by various standard methods such as GI-XRD, electric transport, TOF-ERDA, AFM and UV-vis spectroscopy. Finally, femtosecond time-resolved spectroscopy was used as the most appropriate method for the investigation of complex ground states in nano- sized systems for the detection and characterization of CDW ground state in nanocrystalline grains of these blue bronze films.
