Doped high-temperature and quasi-2D few-layer superconductors: Some theoretical and experimental studies of their fluctuation precursor state and application to the design of optimized photonic superconducting detectors

Vázquez Ramallo, ManuelMartínez Botana, José Martín2025-10-152025-10-152025https://hdl.handle.net/10347/43102This doctoral thesis addresses the study of precursor states of superconductivity in materials of interest, with special attention to very thin-film superconductors and doped cuprate materials. Through a combination of theoretical modeling, numerical simulations, and experimental work, we explored the effects of thermal fluctuations in different configurations of superconducting materials. The fundamental objective is to understand how the precursor state of superconductivity manifests itself, as well as its relevance in technological applications, especially in bolometric detectors based on high critical temperature superconductors.engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/high-temperature superconductorsthermal fluctuationsbolometerpiezoelectricvortex221127 Superconductores220211 SuperconductividadDoped high-temperature and quasi-2D few-layer superconductors: Some theoretical and experimental studies of their fluctuation precursor state and application to the design of optimized photonic superconducting detectorsdoctoral thesisembargoed access
