Development and Design of Self-Sensing SMAs using Thermoelectric Effect
Active research of SMAs has shown that its Seebeck coefficient is sensitive to its martensitic phase transformation and has the potential to determine the SMAs state of transformation. The combination of Shape Memory Alloys, which have a positive Seebeck coefficient, and Constantan which has a …

An analysis of the thermoelectric effect in copper using irreversible thermodynamics
(First paragraph) The treatment of thermodynamics may be classified from two different points of view: the thermodynamic and the statistical mechanical. In the thermodynamic treatment the system as a whole is described by its macroscopic properties, whereas in the statistical treatment the system …

Improvements to solar thermoelectric generators through device design
A solar thermoelectric generator (STEG) is a device which converts sunlight into electricity through the thermoelectric effect. A STEG is nominally formed when a thermoelectric generator (TEG), a type of solid state heat engine, is placed between a solar absorber and a heat sink. When the solar …

Thermal conductivity in organic semiconducting polymers
The thermoelectric effect in materials, which accounts for the direct conversion between thermal energy and electrical energy, has been practically used to build devices for many purposes, including thermoelectric generators for producing clean electricity from temperature difference and …

Photodetectors for graphene-based integrated photonics
… hot-carrier distributions in SLG via the photo-thermoelectric (PTE) effect. Then, I demonstrate PTE-GPDs—fabricated from layered material heterostructures—on a silicon-on-insulator microring resonator. Both detectors operate at Telecom wavelengths (λ = 1.55 μm), are compatible with high-speed (> …
