Abstract
<\/strong>The effect of partial substitution of indium atoms by ytterbium atoms (0.5 and 1 mol%) on the band gap of TlInS2<\/sub> single crystals irradiated with electrons with an energy of 2 MeV and a fluence of up to 1\u00b71016<\/sup> el\/cm2<\/sup> has been studied. The band gap from the measured absorption spectra at room temperature was determined using the Tauc method. It was found that electron irradiation leads to a decrease in the band gap in all TlIn1-x<\/sub>Ybx<\/sub>S2<\/sub> crystals studied. In the range of 77\u2013200 K, the temperature dependence of the exciton absorption band in TlInS2<\/sub> and TlIn0.995<\/sub>Yb0.005<\/sub>S2<\/sub> single crystals was studied.<\/p>

Keywords<\/strong>: semiconductor, rare earth element, exciton, band gap, electron irradiation.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
