Abstract

We have measured the room temperature reflectivity of ZrTe₃, for energies between 0.03 eV and 3.5 eV, with polarizations in the high-conductivity a and b directions. The spectra confirm the semimetallic behavior; a possible gap at 0.435 eV is identified, suggesting that the valence-conduction band overlap is < 0.1 eV. The exptrapolated zero-frequency conductivity is roughly consistent with the d.c. results [5]. The optical scattering times are τ_a = 2 × 10^-15 s and τ_b = 8 × 10^-15 s, and the effective masses are m_ae ∼ 0.2m₀, m_be ∼ 0.3m₀, m_ah ∼ 0.1m₀ and m_bh ≫ m₀.
