Large dielectric constants and massive carriers in La2 CuO4

Year: 1989

Type: article

Abstract: We report measurements of the conductivity and dielectric constant as a function of frequency and temperature on samples of ${\mathrm{La}}_{2}$${\mathrm{CuO}}_{4}$ from dc to 100 GHz. An analysis of the frequency dependence of the complex conductivity indicates that the high-frequency dielectric constant is large (\ensuremath{\simeq}50) and weakly temperature dependent. The dc charge carriers are massive (1100${\mathrm{m}}_{\mathrm{e}}$), weakly damped, and partially pinned.
