| Abstract: | We have measured the far infrared reflectance of NbSe3 and used models of the frequency dependent conductivity to fit the data. General arguments show that at 2 K a charge density wave (CDW) energy gap exists between 120 and 190 cm?1, the relaxation time(s) of the free carriers and CDW pinned mode is >30×10?12 s, and the ratio of the free carrier concentration to band mass is <2×1020 cm?3/m0. |
