Summary

Descripción general del contenido del recurso.

The influence of mechanical processing as well as ion and chemical surface etching of single-crystal germanium on its photoconductivity and photomodulation properties in the terahertz spectral region was investigated. Relative changes in the conductivity of the material under laser illumination at a wavelength of 660 nm and various irradiation powers were determined. A setup was developed for studying the photomodulation properties of germanium at a frequency of 0.13 THz, and a pronounced increase in the absorption of terahertz radiation was revealed even at low illumination powers.
