How do nanostructures affect thermal conductivity?
Nanostructures, such as nanowires, nanotubes, and thin films, can significantly impact thermal conductivity. For instance, materials like carbon nanotubes and graphene show exceptionally high thermal conductivity due to their unique structures. Conversely, the introduction of [nanostructuring]( ) can also reduce thermal conductivity in materials, which is beneficial for applications in thermoelectrics where low thermal conductivity is desired to maintain a temperature gradient.
