Dear all members,
I am trying with a nanodot 10 nm. and lead width 7 nm. to find conductance of the dot under no
crystal defect and also under some missing atoms creating a defect. The system and conductance without
defect is no problem; but I cannot introduce the defect properly in the code and so I cannot get the
conductance. However, in case of quantum wire I have succeeded to build both the defective and not
defective structure and got the conductance. In fact, when the lattice structure is on hexagonal and
bipartite then the problem comes; it is no in case of square lattice. I think I fail to to point out the
location of the atoms in case of spherical dot.
Cheers to all.
