The Effects of Radial Compression on Thermal Conductivity of Carbon and Boron Nitride Nanotubes

الملخص EN

By using molecular dynamics method, thermal conductivity of (10, 10) carbon and boron nitride (BN) nanotubes under radial compression was investigated, and the λ-T (thermal conductivity versus temperature) curves of the two nanotubes were obtained.

It is found that with the increase of temperature the thermal conductivity of two nanotubes decreases; the nanotubes, under both the local compression and whole compression, have lower thermal conductivity, and the larger the compressive deformation is, the lower the thermal conductivity is; the whole compression has more remarkable effect on thermal conductivity than the local compression.
