| Abstract: | Independent measurements at low temperatures of the anisotropic dielectric constant (∈1) of TTF-TCNQ are reported. The measurements utilize dielectric resonance techniques to determine ∈B1 and ∈a1 on the same crystal. The results confirm the unusually large value for ∈b1(4.2 K) > 103 and the anisotropic behavior ∈b1(4.2 K) > 102 found earlier in cavity perturbation studies of TTF-TCNQ. |
