    I’m getting the following error when I run a simulation:

    can’t read “total vstep” : no such variable while executing



  7. How to do simulation on OMEN nanowire tool?

    Open | Responses: 3

    I have changed some input values and tried to simulate the structure but, it was taking around 3 hours to get simulated. Is there easy way to simulate nanowire structure using OMEN Nanowire...


  8. How is the continuous doping density profile implemented in omenwire?

    Open | Responses: 1


    I understand that to mimic the contacts we enforce a high doping density in the source/drain extension regions, and it is easy to do so in a continuum formulation, like the effective...


  9. Why does the potential show a singularity at the location where the boundary condition changes from Dirichlet to Neumann?

    Closed | Responses: 3

    At the gate side, there is a change of boundary condition from Dirichlet to Neumann as we move from the gate to the insulator. Mathematically, this will lead to a singularity in the solution...


  10. boundary conditions for the poisson equation

    Open | Responses: 2

    I have simulated a case where Vg = 0.4V and Vd =0V. However, when I look at the potential plot, it appears that the potential at the boundary where the gate is 0V. Is it simply a plotting...


  11. analytical expression for the poisson solve

    Open | Responses: 1

    May I know what is the rational behind the use of the analytical expression given in the answer I asked about the convergence criteria. In particular, is the analytical formula based on the...


  12. convergence criteria

    Open | Responses: 2

    In the input deck, the poisson convergence criterion is stated as 1e-3. What exactly is the convergence criteria used in omenwire? How much additional computational time will I need if I...


  13. fermi level

    Open | Responses: 2

    In determining the electron density, what fermi levels did you use at the source and drain?

    Thanks, George


  14. Default voltage values need be changed.

    Open | Responses: 2

    With the default device specifications, it seems that the default nanowire has a threshold voltage of ~ 0.6V. So, to drive the device into deep ON state, one should apply gate voltage, probably...


  15. OMEN Nanowire Supporting Document

    23 Feb 2009 | Downloads | Contributor(s): SungGeun Kim, Gerhard Klimeck, Mathieu Luisier

    This material supplements the first-time user guide for OMEN Nanowire with details concerning the limitation of the tool at large gate voltage. At large gate voltage, the calculations of the drain...
