Title: DOS difference
Post by: J.g_johnson on February 21, 2014, 13:23

     I have used VNL 13.8.0 to calculate electrode-molecule-electrode Device Density of State and the result is shown in figure1. So I used VNL2008.10 calculate this device`s DOS again and the result is shown in figure2. Both the result shows that they have the similar trend, but their value are very different, about one order of magnitude difference. I`m not sure which one is right?
     The primary parameters in VNL2008.10 are set as attachment3.

Are you sure these values are in the same unit?

Since the absolute DOS is rarely so relevant, having the two results being similar qualitatively I'd just be happy with that.

Yes
