  1. 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...

  2. 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...

  3. 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...

  4. 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...

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

    Thanks, George

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

    Open | Responses: 1

    Hi,

    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...

  10. 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...

  12. 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...
