Study of the processes caused by these mechanisms, to be able to most effectively and selectively use external influences. popup.description2 The object of research is the synthesis processes and physical properties of chalcogenide glass-like semiconductors (GLS) of the As-S system, as well as methods for preparing future physics teachers to teach nanotechnology. The purpose of the work is to elucidate the physical mechanisms of the formation of optical and electronic properties of nanostructured chalcogenide materials depending on the technological conditions of their production and to develop methodological support for the integration of these results into the system of pedagogical education. Research methods: ampoule vacuum synthesis, spectrophotometry, thermal annealing, physical modeling of the energy spectrum of localized states; pedagogical observation, analysis of the results of students' educational and research activities, scientific project method. Results and novelty: • A critical dependence of the refractive index and width of the As2S3 forbidden zone on the cooling rate of the melt has been established. • It has been proven that precision thermal annealing can significantly increase the radiation resistance of the material by homogenizing the nanostructured glass lattice. • For the first time, the technological cycle of creating new materials has been combined with the methodology of forming the research competence of future physics teachers in the context of STEM education. • An updated laboratory workshop on semiconductor physics for students of pedagogical profile has been developed and implemented. Practical value: the results form the basis for the creation of infrared optical elements and sensors. Methodological developments have been implemented in the educational process of higher education institutions and secondary schools, in particular in the training of students who are members of the Small Academy of Sciences.
