Infrared spectroscopy of Bi2Te2Se

The infrared reflection and transmission spectra of Bi 2 Te 2 Se single crystals grown by the modified Bridgeman method have been studied in the spectral range of 30–10000 cm −1 at temperatures of 5–300 K. The bandgap and its temperature dependence, optical function spectra, and concentration of fre...

Beschreibung
Zusammenfassung:	The infrared reflection and transmission spectra of Bi 2 Te 2 Se single crystals grown by the modified Bridgeman method have been studied in the spectral range of 30–10000 cm −1 at temperatures of 5–300 K. The bandgap and its temperature dependence, optical function spectra, and concentration of free charge carriers in Bi 2 Te 2 Se have been determined.
