Thermoelectric properties of granular metals
We investigate the thermopower and thermoelectric coefficient of nanogranular materials at large tunneling conductance between the grains, gT 1. We show that at intermediate temperatures, T gT , where is the mean energy-level spacing for a single grain, electron-electron interaction leads to an increase in the thermopower with decreasing grain size. We discuss our results in light of the next g...
متن کاملThermoelectric Power in Graphene
Recent years have witnessed considerable interest devoted to the electronic properties of graphene [1-3]. Graphene, a one-atom-thick sheet of carbon atoms arranged in a honeycomb crystal, exhibits unique properties like high thermal conductivity, high electron mobility and optical transparency, and has the potential for use in nano-electronic and optoelectronic devices. With the size of these d...
متن کاملThermoelectric Power Measurements in Wustite
High temperature thermoelectric power measurements were performed on single crystal samples of wustite in equilibrium with a carbon dioxidecarbon monoxide atmosphere. These measurements were made using a "heat pulse" technique which allowed the thermoelectric power of a sample to be determined in a matter of seconds. The short time required for this measurement precluded any possibility of ioni...
متن کاملthermoelectric behavior of packed crystalline granular metals
1 Abstract Loosely packed granular materials are intensively studied nowadays. Electrical and thermal transport properties should reflect the granular structure as well as intrinsic properties. We have compacted crystalline CaAl based metallic grains and studied the electrical resistivity and the thermoelectric power as a function of temperature (T) from 15 to 300K. Both properties show three r...
متن کاملThermoelectric magnetohydrodynamic stirring of liquid metals.
The direct observation of a thermoelectric magnetohydrodynamic (TEMHD) flow has been achieved and is reported here. The origin of the flow is identified based on a series of qualitative tests and corresponds, quantitatively, with a swirling flow TEMHD model. A theory for determining the dominant driver of a free-surface flow, TEMHD or thermocapillary (TC), is found to be consistent with the exp...
