[Wien] LDA+U

[心 陈]

Dear Trond and all users:
          Thank you for your information about LDA+U in my study of HgTe. I set U=7.5 and I got the negative band gap .It's -0.3. That is in accordance with the experimental value. But the energy band of using LDA+U is very different from that of using LDA,that is set U=0.I'm very puzzled with it. Could you tell me something about it?
         On the other hand,if I want to go on with my calculation about properties of HgTe and HgSe, for example its transport properties, which method should I select?LDA+U or not? or other methods.Whether or not that will influence the result.
       Thank you for advance. I will look forward to your reply.
                                                                                                     Mary
