Laser Thermal Tuning by Transient Analytical Analysis of Peltier Device

open access: yesIEEE 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 ...

Peltier effects in Andreev interferometers [PDF]

open access: yesPhysical 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 ...

Peltier effect in normal metal-insulator-heavy fermion metal junctions [PDF]

open access: yes, 2003
A theoretical study has been undertaken of the Peltier effect in normal metal - insulator - heavy fermion metal junctions. The results indicate that, at temperatures below the Kondo temperature, such junctions can be used as electronic microrefrigerators

Employing the Peltier Effect to Control Motor Operating Temperatures

open access: yesEnergies, 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.

New physical principles of contact thermoelectric cooling

open access: yes, 2002
We suggest a new approach to the theory of the contact thermoelectric cooling (Peltier effect). The metal-metal, metal-n-type semiconductor, metal-p-type semiconductor, p-n junction contacts are analyzed.
