Doping Dependent Hopping Mobility : Doping Dependent Hopping Mobility

Requires: Blaze/Organic Display
Minimum Versions: Atlas 5.28.1.R

This example demonstrates the basic characteristics of the doping dependent organic hopping mobility model. The simulations will produce graphs of mobility as a function of doping for an organic material. It demonstrates:

  • Single organic layer definition using Atlas syntax
  • Hopping mobility model specification using the ODEFECTS and MODELS statements
  • Material parameter specification
  • Mobility specification
  • Contact specification
  • DBInternal specification

The template Atlas input deck "" is used to calculate the hopping mobility in an organic material. The doping value is specified using the DeckBuild set command. The parameters of interest (the hopping mobility) are extracted using the " extract from 2d.max.conc " capability.

The content of the template file can be seen inside the input deck file "".

The file "" starts with the GO INTERNAL command which transfers control from the current simulator (i.e. Atlas) to DBInternal. The deck file consists of two main parts:

The LOAD command specifies which template file should be used for multiple runs. The SWEEP command specifies how the variables set in the template file should be changed. In this example, the doping varies from 1e17 to 1e23, and the gamma varies from 2.5e7 to 3.5e7. The number of simulations is set to 14 times 3 (i.e. 42).

The SAVE command tells DBInternal to collate the data generated in all extract commands into the file "organicex03.dat".

After all simulations are complete, the resulting mobility vs doping are plotted in TonyPlot.
