i am working with amorphous silicon, so i tried to add this material by collecting optical constants from the handbook of optical constants of solids. to import data, first i created a .txt file. when i imported the data only 20 data came but there were more than 20 data.
also when i ran the simulation, this error came. the simulation ran successfully with the built in Si-palik material.
what is the solution? any help will be really appreciated. thank you.
