Strong anisotropic thermal conductivity of nanoporous silicon
Nanoporous silicon is known to have a thermal conductivity that is orders of magnitude smaller than the bulk crystalline silicon from which it is formed. Even though the strong columnar microscopic structure of porous silicon indicates the possibility of highly anisotropic thermal properties, there have been no measurements. We report here an experimental investigation of this anisotropy. An an...
متن کاملAnisotropic Thermal Conductivity of Exfoliated Black Phosphorus.
The anisotropic thermal conductivity of passivated black phosphorus (BP), a reactive two-dimensional material with strong in-plane anisotropy, is ascertained. The room-temperature thermal conductivity for three crystalline axes of exfoliated BP is measured by time-domain thermo-reflectance. The thermal conductivity along the zigzag direction is ≈2.5 times higher than that of the armchair direct...
متن کاملAnisotropic thermal conductivity of graphene wrinkles.
In this paper, the anisotropic thermal conductivity characteristics of graphene wrinkles are observed for the first time using a non-equilibrium molecular dynamics method. Our results reveal that the wrinkling level has little effect on the thermal conductivity along the wrinkling direction. However, the wrinkling level plays an important role in the reduction of thermal conductivity along the ...
متن کاملThermal conductivity of B-C-N and BN nanotubes
We have measured the temperature-dependent thermal conductivity T of boron-carbon-nitride B-C-N and boron nitride BN nanotube mats. The thermal conductivity of B-C-N nanotubes is phonon dominated and reflects dimensional effect below 70 K. We employ a new analysis method to estimate the intrinsic T of BN nanotubes converted from B-C-N nanotubes, and find that at room temperature T of a multiwal...
متن کاملAnisotropic Thermal Conductivity of Polycrystalline Niobium for Superconducting Cavities
This study investigates the thermal conductivity Κ of polycrystalline niobium. We recall that superconducting cavities for particle accelerators are made of niobium. And, the thermal conductivity Κ is one of the factors which play an important role in the cooling of these cavities by the surrounding superfluid helium bath. Our experiments revealed a rather unexpected discrepancy in the thermal ...
