Improving the thermoelectric figure of merit [PDF]

open access: yesScience and Technology of Advanced Materials, 2021
The efficiency of a thermoelectric generator and the coefficient of performance (COP) of a thermoelectric heat pump are related to the hot and cold junction temperatures and a quantity known as the figure of merit, zT.

Thermopower, figure of merit and Fermi integrals [PDF]

open access: yesScientific Reports, 2021
The thermoelectric efficiency accounting for the conversion of thermal energy into electricity is usually given by the figure of merit which involves three transport coefficients, with the thermopower, the electrical and the thermal conductivities. These

Thermoelectric System in Different Thermal and Electrical Configurations: Its Impact in the Figure of Merit [PDF]

open access: goldEntropy, 2013
In this work, we analyze different configurations of a thermoelectric system (TES) composed of three thermoelectric generators (TEGs). We present the following considerations: (a) TES thermally and electrically connected in series (SC); (b) TES thermally

Figure of Merit for Servo Motor [PDF]

open access: bronzeNature, 1950
A SERVO motor must control the position of a mechanism (valve, rudder, gear, etc.) in accordance with varying requirements. The figure of merit of such a motor indicates how speedily the motor is able to respond to these requirements.
