Abstract
Linear chain mercury compounds were investigated by measuring the thermoelectric power of Hg2.86AsF6. The temperature dependence of the thermopower above 100K along the â and \( \hat b \) directions exhibits a negative slope which indicates conduction by electrons along the mercury chains and a Fermi energy of 4.6 eV. The slope of the temperature dependence of the thermopower along the ĉ axis exhibits a positive slope indicating hole conduction along the â direction. A transition in the region 180–200 K is observed along the ĉ direction but not along the â direction. A large positive thermopower peak at 13 ± 3 K along both directions is considered to be due to phonon drag. Models are presented to explain the electrical conductivity.
