General Questions and Answers / Strange artefact/bug(?) since last update of QuantumATK
« on: March 17, 2020, 18:16 »
Dear QuantumATK developers,
we recently observed an artefact when switching from QuantumATK version 19.03 to 19.12. The transmission spectra, which we have calculated for two overlapping graphene sheets, shows a transmission of zero in a certain interval around the Fermi energy when using the newer version. You can find the comparison in the attachment including also the input scripts. There is no physical explanation for this artefact and we therefore assume a bug since the recent QuantumATK update (the results using QuantumATK 19.03 make perfect sense).
Thank you in advance.
