[SIESTA-L] unit cell-nanotube

2013-06-17 Por tôpico Drogar
Dear siesta user

Is there any Code to give us coordinate atomic of a arbitrary (n,m)
nanotube?(Or any program)

particularity in a flexible way, so that we can define it (in case of
Graphyne-nanotubes)

Dear drogar,

Download and install demo version 'Nanotube modelar' from foloowing link

http://www.jcrystal.com/products/wincnt/


You can generate any nanotube with coordinates. Note them manually.

Hi,

you can do that at least with:

GDIS http://gdis.sourceforge.net/
VMD http://www.ks.uiuc.edu/Research/vmd/
ASE https://wiki.fysik.dtu.dk/ase/

Try TubeGen (http://turin.nss.udel.edu/research/tubegenonline.html).

A good starting point for CNTs in general is http://nanotube.msu.edu/.

[SIESTA-L] PDOS: Is there a way to specify radius of projection?

2013-06-17 Por tôpico Benedikt Ziebarth

Hello,

I have a question about PDOS calculations with siesta. Is there a way to 
specify the radius around the atoms in which the projection is carried 
out? This option exists in different other dft codes like vasp 
(http://cms.mpi.univie.ac.at/vasp/vasp/RWIGS.html).

Any help would be very welcome.
Thanks

Benedikt Ziebarth

Hi Benedikt,

SIESTA does not need projections, as the basis orbitals are localized on
the atoms. You get naturally the chemical information one is used to.
Plane-wave codes such as vasp do need projections to get some kind of
local information from the delocalized basis.
