$addbiascontact is a command to provide extra fixed bias contact. The command is as following

  $addbiascontact
  N  
  type1   Bias1   barrier1 
  type2   Bias2   barrier2 
   ...
  typeN   BiasN   barrierN
   

Type = 1:  Schotkky barrier, Provide Schottky barrier related to Ec
Type = 2:  Schotkky barrier but us affinity , Provide the metal workfunc
Type = 3:  barrier decided by dopant density ( doping density should not be zero) 

Bias : The applied bias 
barrier :  The Schotkky barrier  (or work function) depending on type 1 or 2

For example

  $addbiascontact
  2  
  1   2.0  1.2
  2   3.0  4.3   (4.3 is the electron affinity) 

Note: if type == 2, the function $ifaffinity should be activated
