Abstract

Infrared absorptance measurements of polycrystalline silicon and single crystals of silicon having oxygen and carbon impurities were carried out at low temperatures in the wavelength range of multiphonon infrared absorption of silicon. Peak absorptance and frequencies were measured at temperatures from 10 to 130 K at intervals of 10 K. Absorptance-temperature curves were plotted for multiphonon bands and impurity bands. It has been observed that the three phonon band [2 TO (Γ) + TA (L)] exhibits a resonance-like behaviour with the anti-stretching mode of Si-O at low temperatures.
