Absence of anomalous Nernst effect in spin Seebeck effect of Pt/YIG

AIP Advances, 2016
The Pt/YIG structure has been widely used to study spin Seebeck effect (SSE), inverse spin Hall effect, and other pure spin current phenomena. However, the magnetic proximity effect in Pt when in contact with YIG, and the potential anomalous Nernst ...

Improving the Thermoelectric Properties of Conjugated Polymer Thin Films by Dip Coating – but not through Alignment

Advanced Electronic Materials, EarlyView.
The study demonstrates that dip coating at lower speeds significantly enhances the thermoelectric performance of P3HT by improving electrical conductivity. Contrary to expectations, this improvement is seemingly not due to polymer alignment but rather to better structural order achieved during slower solvent evaporation at lower dip coating speeds ...

Novel Phosphazenium Tetrafluoroborate Dopant Enables Efficient and Thermally Stable n‐Doped Organic Semiconductors

Advanced Electronic Materials, EarlyView.
A novel n‐dopant, phosphazenium tetrafluoroborate (P2BF4), is introduced for efficient n‐doping in N2200, P(PzDPP‐CT2) and other organic semiconductors (OSCs). P2BF4‐doped OSC films exhibit exceptional thermal stability, maintaining electrical conductivity after heating at > 150 °C for 24 h. This stability allows organic thermoelectric devices based on

Bandgap‐Dependent Doping of Semiconducting Carbon Nanotube Networks by Proton‐Coupled Electron Transfer for Stable Thermoelectrics

Advanced Electronic Materials, EarlyView.
Proton‐coupled electron transfer doping with benzoquinone is applied to p‐dope dense films of semiconducting single‐walled carbon nanotubes. The doping efficiency depends on the pH of the doping solution and the bandgap of the nanotubes. The highest conductivities and power factors are achieved for small‐bandgap nanotubes, remaining stable for over 120

Thermoelectric Properties of a Family of Benzodifuranone‐Based Conjugated Copolymers in Oriented Thin Films Doped Sequentially With NDMBI‐H

Advanced Electronic Materials, EarlyView.
Combining high polymer orientation of n‐type copolymers by temperature rubbing and sequential doping with N‐DMBI results in a strong improvement of electrical conductivity and thermoelectric power factors reaching up to 9.8 ± 1.6 S cm−1 and 8 ± 3 µW m−1.K2, respectively.

A Sensitive Thermoelectric Respiratory Sensor Using a Hollow-Square Structure of Cubic Silicon Carbide-Based Heterojunction. [PDF]

Small
A sensitive self‐powered respiratory sensor is developed using a hollow‐window structure implemented on a 3C‐SiC/Si heterojunction‐based platform. This design enables the manipulation of thermal transport with the heterojunction regulating the flow of thermally generated charge carriers, yielding a significantly higher output thermal voltage than that ...
