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…
Electrical transport and thermoelectric properties of silver nanoparticles
Vikash Sharma, Gunadhor Singh Okram
Debye temperature decrease, residual resistivity increase and electron-phonon coupling constant increase as crystallite size decreases have been found from electrical resistivity i…
Size-induced structural phase transition at ~6.0 nm from mixed fcc-hcp to purely fcc structure in monodispersed nickel nanoparticles
Tarachand, Vikash Sharma, Jaiveer Singh +5
We have investigated the core issue of atomic lattices in monodispersed Ni nanoparticles (NPs) of sizes 3.8 nm to 10.1 nm using detailed analysis of X-ray diffraction, synchrotron…
