Metal to Insulator Transition, Colossal Seebeck Coefficient and Large Violation of Wiedemann Franz law in Nanoscale Granular Nickel
Vikash Sharma, Gunadhor Singh Okram, Yung-Kang Kuo
We report on the electrical and thermal transport properties of nickel nanoparticles with crystallite size from 23.1 to 1.3 nm. These nanoparticles show a systematic metal to insul…
Ultralow Thermal Conductivity and Large Figure of Merit in Low-Cost and Nontoxic Core-Shell Cu@Cu2O Nanocomposites
Vikash Sharma, Gunadhor Singh Okram, Divya Verma +2
Identification of novel materials with enhanced thermoelectric (TE) performance is critical for advancing TE research. In this direction, this is the first report on TE properties…
Metal to insulator transition, colossal Seebeck coefficient and ultralow thermal conductivity in solution-processed monodispersed nickel nanoparticles
Vikash Sharma, Gunadhor Singh Okram, Yung-Kang Kuo
We report here metal to insulator transition, colossal Seebeck coefficient and ultralow thermal conductivity (0.0057th of its bulk value, significantly smaller than many well-known…
Doping evolution of Zhang-Rice singlet spectral weight: a comprehensive examination by x-ray absorption spectroscopy
Y. -J. Chen, M. G. Jiang, C. W. Luo +7
The total spectral weight \textit{S} of the emergent low-energy quasipaticles in high-temperature superconductors is explored by x-ray absorption spectroscopy. In order to examine…
Nonstoichiometric doping and Bi antisite defect in single crystal Bi2Se3
F. -T. Huang, M. -W. Chu, H. H. Kung +6
We studied the defects of Bi2Se3 generated from Bridgman growth of stoichiometric and nonstoichiometric self-fluxes. Growth habit, lattice size, and transport properties are strong…
Sodium ion ordering of Na0.77CoO2 under competing multi-vacancy cluster, superlattice and domain formation
F. -T. Huang, G. J. Shu, M. -W. Chu +4
Hexagonal superlattice formed by sodium multi-vacancy cluster ordering in NaCoO has been proposed based on synchrotron X-ray Laue diffraction study on electrochemicall…
