Dear all
?I want to calculate the density of state of graphene but there is a problem
that it is?extremely variant by changing the parameters.?the best plot
of?DOS?that I could find is?linear?at fermi energy but there is a gap there.
what is the reason of these variation? and which parameters should be?adjusted?
would you give me an input?which you know it gives a good resault. the
potential that?I use is in LDA approximation.
thank you.
