    High School Are waves always associated with heat?

    maybe only phonon waves can cause the heat.

    High School Are waves always associated with heat?

    I think so, like phonon waves.

    Graduate What's the relationship between phonon spectrum and thermal conductivity

    I read some literature about the analytical model for the thermal conductivity of nanostructures, fount that there are two methods for us to get the thermal conductivity from the phonon properties: phonon spectrum method; wave vector method. You can see the details in Patrice Chantrenne's...

    Graduate What's the relationship between phonon spectrum and thermal conductivity

    Thank you!Your reply is vividly,it did help me a lot about the physical meaning of phonon and the thermal conductivity. May I ask you another question? If I got spectra of two materials at the same temperature, how can I distinguish which material's thermal conduction is better (more...

    I mean how can i analysis the thermal conductivity of two structures with their phonon spectrum. thank you!
