<div>Thank you Pablo<br>
</div>
But I am required to connect two Si atoms at the surface to reduce one dangling bond and then put H or may be H is not needed if both of the dangling bonds have possibility of omitting. I am reading the paper but could not understand although Fig. 2 is looking
easy to understand. WHat is 2*1 or 2*2 or 2*4 ? are the super-cells like 2*1*1 or 2*2*1 etc.<br>

<p>This is the same that I simplified and symmetized. If you are going to add H then you need set the space group as P1 (#1) so the H can move freely and not in a symmetrical path.</p>
<p>Now, if you use my proposed structure then you can put inversion (SG P-1, #2) and add two H, one on each surface, but in a symmetric way.</p>
<p>Other thing, maybe my proposed structure is too small and your structure is ok, but I would symmetrize as I explained in an earlier message.

<div>Dear Users<br>
</div>
Kindly guide me how to reconstruct Si 100 layer? The Si 100 structure is attached here with. It has two dangling bonds on both surfaces (Top and Bottom). My intension is to keep one dangling bond on the top and bottom surfaces that will be saturated by H addition.
