<div>Dear Users,<br>I have some questions:</div>

<div><font size="4">1.</font> How to get the Electron density differences from Wien2K. <br>For example, GaN with hexagonal structure, </div>

</div>
<p><font size="4">2.</font> If I want to plot the electron density distributions in several energy regions, such as: (1)-16 ~ -15ev, (2) -2 ~ -1ev with respect to EF, which input file should be changed? </p>
<p><font size="4">3.</font> If I want to get the Cohesive Energy of this crystal, I should calculate the total Energy of the bulk GaN, the free Ga and N atom, then E<font size="1">coh</font> = - E<font size="1"> bulk</font>
+ E<font size="1">Ga</font> + E<font size="1">N</font> OR need + E<font size="1">correct</font>? and how to do it?<br>For the binding energy of the N2 dimer, I had found some suggestions in the list, but I still don't know how to set the *.struct file about N2, isn't like the follow:
<br>N-N length is set as 2.08 Bohr! Then RMT=??? <br><font size="1"><em>P LATTICE,NONEQUIV.ATOMS: 2 <br>MODE OF CALC=RELA

<div><font size="4">4.</font> Can someone give me *.klist files template or the high symmetry piont's coordinates of this hexagonal structure and wurize structure use for bandstruct calculation? </div>

<div> thanks a lot!</div>
