The work focused primarily on the high-temperature superconductor Bi-2212. Single crystals were grown using two different methods, optimal synthesis conditions were established, and high-quality samples with critical temperatures above 90 K were obtained. Transport and spectroscopic measurements confirmed the stability and reproducibility of the material’s properties. An innovative approach to analysing ARPES data using convolutional neural networks was developed. The model incorporates key features of the superconducting and pseudogap states and enables automated detection of bilayer splitting in the spectra. This method significantly accelerates the interpretation of large ARPES datasets and improves the consistency of the analysis. A high-vacuum magnetron sputtering system was also installed, providing the capability to synthesize new quantum materials in thin-film form and supporting future investigations. Altogether, the achieved results establish a modern platform for accelerated discovery and study of quantum materials and strengthen the Ukrainian–German scientific collaboration in this field.
