Dears:
When i use siesta to calculate the graphene's optical properties,it
always come to a question at last that said"Do you want to include a Drude
term? if yes:enter 1,if no:enter 0"Since i konwn,this is typically needed for
metals,i don't known whether it needed for graphene?When i enter 1 or 0,it has
nothing to do with the results,i don't known why.If i want it include the Drude
term ,which command shoud i use?Thank you very much!
