      Hi, I want to create a spherical si quantum dot with a 5nm radius in a solar cell structure. how can i create this quantum dot in FDTD? please explain to me step by step

      One way is to add a sphere with radius of 5nm. It will need much finer mesh to geometrically resolve it, say at least 6 meshes for the sphere. It will take longger wallclock time since the time step is very small compared to the solar spectrum, with average wavelength 0.55um (period ~1.8 fs).
