Dear sir,<br><br>
Thank you very much for your reply. <br>It's very kind of you to point out my misunderstanding on calculation of binding energy. <br>Now, my work seems to be further improved. Thank you again.<br><br>vega<br><br><div class="gmail_quote">

</div>binding energy = E(water+surface)-E(surface)-E(water).<br>
All energies should be calculated with the same cell,<br>
cutoff, k-points, at the equilibrium geometry of the<br>
respective system, i.e. E(water) for an isolated water<br>
molecule, not the water molecule in the geometry after<br>
adsorption<br>
