Title: Device calculations are not consistent for the same system?
Post by: Zalman_chu on February 6, 2018, 03:41

We calculated a p-i-n device with the same finite bias several times by using  ATK 2017.2, however, although the calculations are all converged, the results are quite different for the same system. We found :
Fresh calculation gives completely different results as compared with calculation started from a converged calculation, the details is shown in figure attached.
Thank you for your help !

Please send these figures together with the python scripts and log files for each of the three calculations to support@quantumwise.com.
