The photothermoelectric (PTE) effect enables efficient harvesting of the energy of photogenerated hot carriers and is a promising choice for high-efficiency photoelectric energy conversion and photodetection. R
An approach using the photothermoelectric (PTE) effect, in which an electrical signal is generated in response to the material thermoelectric effect and the temperature difference in the carrier system caused by incident light irradiation, has recently emerged. In a study of the PTE effect in grap...
The in-plane thermoelectric power () of single-crystal graphite in the presence of a magnetic field applied parallel to the c direction was measured at temperatures (T) from 4.2°K up to 300°K. With an increase of the field intensity (H), the sharp negative dip of the versus T ...
nanoribbons Ming-Xing Zhai1,2 & Xue-Feng Wang1,3 We demonstrate that the giant magnetoresistance can be switched off (on) in even- (odd-) width zigzag graphene-like nanoribbons by an atomistic gate potential or edge disorder inside the domain wall in the antiparallel (ap) magnetic ...
Furthermore, our value is over three times larger than that of Bi2Te3, the commercially used inorganic p-type TE material (~4.5 mW m−1 K−2)9, and is approaching the highest PF achieved at room temperature by 2D materials: monolayer graphene (36.6 mW m−1 K−2)10. Note that...

The film shows free-electron-like charge transport properties, with an enhanced Hall mobility, and an increased Seebeck coefficient compared to the CP on graphene that is prepared without 3D tectons. A magneto-thermoelectric (MTE) effect is reproducibly observed for the film device. Taking advantage...
