A novel current-induced thermoelectric phenomenon, the nonlinear anomalous Ettingshausen effect, was discussed. As an example, the weak charge ordering state in an organic conductor α-(BEDT-TTF)2I3 was focused on. This effect generates a transverse heat current with rectifying characteristics, namely unidirectionality even under AC fields.

Transistor Model

A model of a thermal transistor to control heat flow is reported. Like its electronic counterpart, the thermal transistor is a three-terminal device with the important feature that the heat current through two terminals can be switched or modulated by the temperature of the third terminal. The thermal transistor model is possible because of the negative differential thermal resistance.

Apparent Similarity

Organic conductor (DMTSA)BF4 [DMTSA: 2,3dimethyl-tetra-sleno-antracene] is a compound composed of an electron donor DMTSA and a monovalent acceptor BF$_4^-$. In the salt, the electronic system is expected to be the Mott-Hubbard insulator. However, its conductivity at room temperature is 200~400$\Omega^{-1}$cm-1 and behaves metallic above ∼2OOK. At ambient pressure, we found anomalies both in the DC conductivity components and in the permittivity at ~80K, similar to those in (TMTTF)2X associated with charge ordering at ~100K. In the insulating state under low pressure, we found that the sample shows non-linear conduction with threshold. We discuss the possible origin of the anomalies and the apparent similarity with the non-linear electric conduction by the density wave sliding.
