“…If there was a fluctuation in the x parameter, then these regions could affect the piezoelectric signal more than the grain boundaries do. Such compositional disorders were observed and analyzed in other mixed crystals: Cd 1−x Mn x Te and Zn 1−x Be x Te [23,24].…”

This article presents the numerical analysis of the amplitude and phase piezoelectric spectra of a group of mixed crystals of the Zn 1−x−y Be x Mn y Se type. After growth treatment of mixed crystals, such as grinding, polishing, and etching, some surface defects have been created whose energy levels are in the region of the band gap of the material. The lower the concentration of these defects is, the smaller amplitude of the photothermal signal in this energy region is expected and the higher the quality of such a crystal surface is. This article focused on the study of the application of photothermal piezoelectric method for investigation of the surface energy levels and their corresponding absorption bands in the energy-gap region of the material.

Photothermal and optoacoustic spectroscopy: state of the art and prospects

et al. 2022

View full text Add to dashboard Cite

The main issues and areas of application of photothermal and optoacoustic spectroscopy are reviewed. Progress in innovative techniques in the most actively developing areas is presented, including microspectroscopy, multispectral techniques, the measurements of single particles and objects with a resolution better than the diffraction limit (nanoscopy) by both optical and probe-based methods. Possible applications of photothermal and optoacoustic spectroscopy for determining the properties of materials, studying photochemistry and fluorescence, chemical reactions, and analytical and applied chemistry, and solving biomedical problems is discussed. Some prospects for the development of these methods are presented.
