Ukrainian Journal of Physics| Резюме: | Optical research of the transmittance and reflectance spectra of p-CdTe(111) single crystals and Cd0.9Zn0.1Te solid solution specimens in a spectral interval of (0.8÷1.7×10−6 m before and after their laser irradiation at the wavelength Λ = 266 nm to energy doses of 17.2–47.01 mJ/cm2 has been carried out. The structural gettering, i.e. the absorption due to the presence of regions in semiconductors with a defect structure that can actively absorb point defects and bind impurities, was found to be the main mechanism of influence of a pulsed laser radiation on the optical properties of thin near-surface layers in the studied crystals. |
