Dear experts,

I used the hdp.py file from tutorial "Modeling metal–semiconductor contacts: The Ag–Si interface" to make average of my EDP result. http://docs.quantumwise.com/casestudies/ag_si_interface/ag_si_interface.html

Please see the attached figure of the device: the total length of the device is about 90nm. However, the result from hdp.py just showed me a region from 10nm-80nm.  Since I am not very familiar with python script, can anyone here help me to explain why it cannot display the full length of the device in the hdp.py?

BTW, I am using ATK2015.1, together with ATK2016.4.

Thank you very much for your time and kind help!

The averaging procedure will in general not give reasonable average potentials in the ends of the x-range, so in script line 531 the x-axis limits are set according to variables that are calculated from the averaging parameters. Simply comment out line 531 in order to see the full range.
