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 ...
photothermoelectric effect was in low-dimensional materials, such as carbon nanotubes, III–V semiconductor nanowires, dichalcogenide materials, and graphene. Researchers in China and the USA, led by Zhiqiang Guan and Hongxing Xu at Wuhan University, China, extended this effect to silicon nanomaterials...
while ions were modeled using the OPLS-AA force field74. For carbon atoms on graphene, LJ potential parameters were sourced from the CHARMM27 force field75. Water was described using the SPC/E model. The structure of COFs was optimized by Gaussian 09 package76with the implicit solvent model ...
In this work we report on opportunities for a colossal reduction in lattice thermal conductivity (LTC) of graded micro-nanoporous structures with inhomogeneous porosity which leads to the considerable improvement in thermoelectric figure of merit ZT. We employ the effective medium theory to calculate ...
Here we report on giant magnetothermoelectric effect in Al2O3 magnetic tunnel junctions. The thermovoltage in this geometry can reach 1 mV. Moreover a magneto-thermovoltage effect could be measured with ratio similar to the tunnel magnetoresistance ratio. The Seebeck coefficient can then be tuned...
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...
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.Recently,the PTE effect was reported in low-dimensional nanomaterials,suggesting the possibility of ...
