General Questions and Answers / Why the unit of LDOS is different between ATK2008.10 and ATK2011.2?

« on: May 2, 2011, 06:12 »

Dear everyone,
The unit of LDOS in ATK2008.10 is (Angstrom)^(-3)*(eV)^(-1),and in ATK2011.2 (Angstrom)^(-3). Why they are different? Which one is right? Or are they both right?
Thanks a lot.

General Questions and Answers / transmission pathways calculated under nonzero bias voltages or gate voltages?

Hello,everyone,
       Can the transmission pathways be calculated under nonzero drain-source bias voltages or gate voltages?
       Thanks a lot.

General Questions and Answers / Re: Why the transmission spectrum cannot be plotted using "huckel-analyzer.py"?

I get the same problem, but it works fine in ATK 11.2.b2 which I suggest you download and use for your evaluation instead.

Thank you very much.

General Questions and Answers / Why the transmission spectrum cannot be plotted using "huckel-analyzer.py"?

Dear all,
            I just begin to learn ATK step by step with the tutorial. I meet a problem in the process of redoing a example of the tutorial:
            I  select the script "huckel-analyzer.py" in VNL file browser and drop the script onto the Custom Analyzer tool of VNL10.8.2，then drop the Li-H2-Li system onto the Device-Configuration box. But the transmission spectrum doesn’t appear, while the MolecularEnergySpectrum, Bandstructure, DifferencePotential can appear. But in the tutorial "http://www.quantumwise.com/documents/manuals/latest/VNLTutorial/XHTML/chap.analyzertools.html#sect1.analyzertools.builder", the transmission spectrum can also appear.
            Is there any wrong with my work? Or any other cause?
            Thanks a lot.
