doping with known concentration levels
« on: February 3, 2011, 12:46 »
sir,

i want to have a channel region with Linear doping concentration of 0.1365A-1.how can this be implemented in atk (i.e doping with a certain concentration level)?

and regarding the reply given for the work function,it was mentioned that its not possible to set the work function parameter,except during post analysis..how is this possible during post analysis when the work function of the default metallic region is not known.

For a given concentration level of doping, it may correspond to too many possible atomic configurations, especially for the case with inhomogenous distribution of dopant. Therefore it is difficult to figure out which one is the possible one in the simulation. That is to say, one cannot simulate the case with a given concentration level of doping in a straightforward manner. The crude approximation is to consider the homogenous distribution of dopant.

For a metal, its work function can be computed via ab-inito calculation.
