Optical Properties of Tellurium-Based Chalcogenide Alloys in the Far Infrared Region (λ > 30 μm)
Ternary telluride alloys of Ge–Se(Sb)–Te and Si–Ge(Ga)–Te systems are synthesized in glassy and crystalline states for use in the terahertz frequency range. The transmission spectra of the obtained alloys are measured and studied in a wide wavelength range from 0.75 to 300 μm. The possible mechanism...
