Low Temperature Far-Infrared Transmission Properties of Polycrystalline and Single-Crystal Silicon

Volume 22, Number 3 (June 1968) Page 212-213

Durig, J.R.; Bush, S.F.; Baglin, F.G.

Fateley et al. have reported that the far-infrared spectrum of polycrystalline silicon at room temperature has a 50% transmission curve from 30-500 cm−1 We wish to report the appearance of three bands in similar material upon cooling to liquid-nitrogen temperature. A standard low-temperature cell was used for the measurements. A Beckman model IR-11 spectrophotometer and a Perkin-Elmer 521 spectrophotometer were used to record our data.
