Resumo

The main technological and difficult-to-determine impurities in h-BN are carbon and oxygen. In production, there is a need for quality control with high spatial resolution of both individual h-BN nanolayers and heterostructures based on it. The aim of the work is to develop a method for non-destructive testing of the defects and impurity composition of h-BN thin layers by Raman scattering and cathodoluminescence spectrometry. A literature review of the features of the material of hexagonal boron nitride and its luminescent properties is performed. The samples were measured using a Raman spectrometer, a scanning electron microscope with a cathodoluminescent attachment, and an electron probe microanalyzer. The analysis of the obtained results is performed. Areas of application: diagnostics and quality control.
