Title: Accuracy of the calculated results
Post by: FlyFlower on February 17, 2011, 02:36

hello everyone. as we know that the coherent electron transport scheme is only applicable to the low-voltage regime (usually not beyond 1 V). phonon-assisted electron transport may be dominant at high voltages. so how can ensure our results in range (-3v, 3v) obtained by using atk? thank you very much.

There are certainly many cases where phonon-assisted transport is relevant - and many cases where it is not, even at high bias. For every calculation of this type you make a certain set of fundamental assumptions that define the scope of the model. ATK operates in the regime where phonons are not taken into account.
