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 mass …

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 when we …

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 error, or …

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 …
