چکیده
Polycrystalline Platinum Nanofilms Q. G. ZHANG, B. Y. CAO, X. ZHANG, M. FUJII and K. TAKAHASHI, J. Phys.: Condens. Matter, 2006, 18, (34), 7937–7950 The thicknesses of the studied polycrystalline Pt nanofilms (1) ranged from 15.0–63.0 nm and the mean grain sizes varied from 9.5–26.4 nm. The thermal conductivities of (1) measured by a direct electrical heating method are greatly reduced from the bulk values, due mainly to grain-boundary scattering.

Multiscale modeling of thermal conductivity of polycrystalline graphene sheets.
We developed a multiscale approach to explore the effective thermal conductivity of polycrystalline graphene sheets. By performing equilibrium molecular dynamics (EMD) simulations, the grain size effect on the thermal conductivity of ultra-fine grained polycrystalline graphene sheets is investigated. Our results reveal that the ultra-fine grained graphene structures have thermal conductivity on...

We present preliminary results of a theoretical investigation of the thermal conductivity of polycrystalline GaN films. It is assumed that grain boundaries play a major role in limiting the thermal conductivity, which is calculated using the phononhopping transport approach. The effect of the grain size, size dispersion, and inter-grain interface structure on the thermal conductivity values is ...

We conducted extensive molecular dynamics simulations to investigate the thermal conductivity of polycrystalline hexagonal boron-nitride (h-BN) films. To this aim, we constructed large atomistic models of polycrystalline h-BN sheets with random and uniform grain configuration. By performing equilibrium molecular dynamics (EMD) simulations, we investigated the influence of the average grain size...

متن کاملNanograin effects on the thermoelectric properties of poly-Si nanowires
In this work we perform a theoretical analysis of the thermoelectric performance of polycrystalline Si NWs by considering both electron and phonon transport. The simulations are calibrated with experimental data from monocrystalline and polycrystalline structures. We show that heavily doped polycrystalline NW structures of grain size below 100nm might offer an alternative approach to achieve si...
