摘要：

This work reports a study of the optical and electrical properties of tin monoselenide SnSe and tin dichalcogenides SnX2 with X = S and Se. The semiconducting character of the single crystals is investigated by means of resistivity and Hall effect in the temperature range from 90 to 300 K. The energy gap data are obtained by absorption measurements. The far-infrared reflectance spectra of the tin chalcogenide compounds have been measured. The experimental data are fitted using a four-parameter dispersion model based on the factorized form of the dielectric function.
