[Pw_forum] problem with layer dos

[Giuseppe Mattioli]

Ok, you've been eventually able to set up a correct GaN wurtzite structure. But why do you expect that a GaN monolayer embedded in  vacuum is a 
semiconductor? Now that you have understood the structure, you should read at least few of the (many...) theoretical and experimental papers written 
on GaN bulk and surfaces. If I am allowed for further advice, calculations are not easy shortcuts to skip everything else.
As I said above, there are tons of related papers. You may want to start with this one, which can tell you something interesting about bulk GaN and 
semiconductor simulations
