Nano-Scale heat conduction
Hi Support team,
We know that Heat conduction in macrostructures is typically treated as a diffusion process governed by Fourier law:
where q is the local heat flux and DT the temperature gradient, k is the thermal conductivity of the material that is temperature-dependent.
However, in nanoscale, this behavior is highly questionable.
So, how does Lumerical calculate its thermal conduction in nanoscale devices? Do you use some specific model? If so, please elaborate on it.
Let's say I use HEAT solver, for simulating a changes in index of refraction along the nanoscale device due to heat source located on the other side. So in this case, how the temperature distribution is calculated along the nanoscale device, according to what model?
