nextnano3 - Input file generator 1D

Next Generation 3D Nano Device Simulator


Step 2: Specify doping and impurities

This step is a little bit tricky. You have to submit this form several times. The first time, a new file is generated on our server and the first doping is added to this file. The second time, the second doping is added to this file. (Be sure to change "first doping" to "no"). For the last doping, you will have to indicate that you won't add another doping.

Hint: If you want to generate something like a "superlattice" doping you can open this window two or more times and submit them alternately.

BEGIN Is this your first doping? * yes  no    (!!!!!!!!)
Chose yes only for the first time.
END Is this your last doping? * yes  no    (!!!!!!!!)
Chose yes after you sample is finished.
  Include doping and impurities? * yes no

The script will generate a file called doping_part_beta.txt on our server.

* must be filled out if doping yes
