scattering current is larger than ballistic current

Dear Sellier, 1. I am new to Archimedes simulations. I tried to run the example code diode.input as such without any modifications. The result I obtained is embarassing. set1
ACOUSTICSCATTERING ON OPTICALSCATTERING ON Right Edge : Electron Current on contact #1 = -29.0805 (A/m) Left Edge : Electron Current on contact #1 = -33.2198 (A/m) set2
ACOUSTICSCATTERING ON OPTICALSCATTERING OF Right Edge : Electron Current on contact #1 = -20.2275 (A/m) Left Edge : Electron Current on contact #1 = -29.9472 (A/m) set3
ACOUSTICSCATTERING OFF OPTICALSCATTERING ON Right Edge : Electron Current on contact #1 = -24.4602 (A/m) Left Edge : Electron Current on contact #1 = -27.2556 (A/m) set4
ACOUSTICSCATTERING OFF OPTICALSCATTERING OFF Right Edge : Electron Current on contact #1 = -6.03271 (A/m) Left Edge : Electron Current on contact #1 = -19.9581 (A/m) So, it seems that when scattering is off, the current is least and when both scattering are on, the current is maximum. It may be my mistake, can you figure out what happened? 2. How will we include impurity scattering: IMPURITYSCATTERING ON? 3. Is it possible to simulate 10nm devices with this version? If not, what must be the modifications? I expect a reply from you when you are free to look into these things. Thank you very much for providing such a wonderful code for open access.

    Hello Joseph,

    Sorry for the late reply.

    In order to answer to your question, I need more details. What is the final time you are using in your simulations? I am asking to understand if you reach the stationary regime. If this is not the case, then your computed currents are obviously wrong.

    Please, let me know.

    Regards,

    JM Sellier
