How is the continuous doping density profile implemented in omenwire?
Q&A|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...

Why does the potential show a singularity at the location where the boundary condition changes from Dirichlet to Neumann?
Q&A|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...

OMEN Nanowire Supporting Document
23 Feb 2009 | | 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 current can be incorrect when the Poisson solver in OMEN does not converge. This problem is not...
