Title: ripple effect
Post by: ramkrishna on August 28, 2012, 08:37
Dear Sir,
 Is it possible to include ripple effects on 2D materials and their transport properties?

Regards
Ramkrishna

You can study any atomic system you want, you just have to set up the geometry accordingly.

Dear Sir,
 Yes, I can understand :) but my question was, how can I make a rippled geometry in ATK (like http://prb.aps.org/abstract/PRB/v83/i12/e125422 , http://prb.aps.org/abstract/PRB/v83/i16/e165434 , http://scitation.aip.org/getpdf/servlet/GetPDFServlet?filetype=pdf&id=JAPIAU000104000011113536000001&idtype=cvips&doi=10.1063/1.3032895&prog=normal)?

Yes, it's certainly possible, you just need to apply a periodic transformation to the coordinates in the Builder "Coordinate Tools>Transform by Expression". Or, you can install the attached prototype plugin, it will do it for you a little bit easier. However, I think it's important to realize that the structure in the referenced article is large (20,000 atoms) and also is obtained as a result of (not as input to) a calculation, viz. an MD simulation. Which, of course, you could carry out in ATK using the Brenner potential, which certainly should be able to handle 20,000 atoms.

. But can't understand which plugin is this, and also could not find any attached file here.

Classic mistake - forgetting the attachment. Let me double-check a few things to make sure the plugin works properly, and then I will attach it later today!
