Strongly nonlinear thermovoltage and heat dissipation in interacting quantum dots [PDF]
, 2014 We investigate the nonlinear regime of charge and energy transport through Coulomb-blockaded quantum dots. We discuss crossed effects that arise when electrons move in response to thermal gradients (Seebeck effect) or energy flows in reaction to voltage ...

Peltier effects in Andreev interferometers [PDF]
Physical Review B, 2007 The superconducting proximity effect is known to modify transport properties of hybrid normal--superconducting structures. In addition to changing electrical and thermal transport separately, it alters the thermoelectric effects. Changes to one off-diagonal element $L_{12}$ of the thermoelectric matrix $L$ have previously been studied via the ...

Laser Thermal Tuning by Transient Analytical Analysis of Peltier Device
IEEE Photonics Journal, 2017 In any wavelength sensitive application, extensive care should be taken in addressing the wavelength drift issues. In the case in which laser tuning is conducted by using thermoelectric cooler, an accurate expression is needed to describe transient ...

A Soft Robotic Cover with Dual Thermal Display and Sensing Capabilities [PDF]
, 2020 We propose a new robotic cover prototype that achieves thermal display while also being soft. We focus on the thermal cue because previous human studies have identified it as part of the touch pleasantness.

Longitudinal spin Seebeck coefficient: heat flux vs. temperature difference method [PDF]
, 2017 The determination of the longitudinal spin Seebeck effect (LSSE) coefficient is currently plagued by a large uncertainty due to the poor reproducibility of the experimental conditions used in its measurement.

High-throughput imaging measurements of thermoelectric figure of merit
Science and Technology of Advanced Materials: Methods, 2021 We demonstrate a method for the simultaneous determination of the thermoelectric figure of merit of multiple martials by means of the lock-in thermography (LIT) technique.

Employing the Peltier Effect to Control Motor Operating Temperatures
Energies, 2023 Electrical insulation failure is the most common failure mechanism in electrical machines (motors and generators). High temperatures and/or temperature gradients (HTTG) are the main drivers of insulation failure in electrical machines.

Improved Thermoelectric Cooling Based on the Thomson Effect [PDF]
, 2012 Traditional thermoelectric Peltier coolers exhibit a cooling limit which is primarily determined by the figure of merit, zT. Rather than a fundamental thermodynamic limit, this bound can be traced to the difficulty of maintaining thermoelectric ...

Theory of the spin Peltier effect
Physical Review B, 2017 A microscopic theory of the spin Peltier effect in a bilayer structure comprising a paramagnetic metal (PM) and a ferromagnetic insulator (FI) based on the nonequilibrium Green's function method is presented. Spin current and heat current driven by temperature gradient and spin accumulation are formulated as functions of spin susceptibilities in the PM
