Format:

 $ElBoundary   
boundary number
surface_number(in GMSH) contact_type schottky_adjust_value "contact bias"  ("contact bias"  is only used if contact_type is 1001)


For example:

$ElBoundary                           
2
10  4  0.00     
80  3  0.00    
200 1001  0.5  -2.0


note that: 3 drain 4 sorce 2 gate 21 no current gate 5 is base contact, 1001 is the addtional contact bias type which is always schottky contact

200 1001  0.5  -2.0 means surface 200 has 1001 contact, the contact type is Schottky type. The barrier is 0.5eV if affinity is not used
bias voltage is -2.0V.
If $affinity is used, 0.5eV is the electron affinity. 


For example2:

$ElBoundary                           
2
10  2  0.00     
80  2  +/-0.50    

if there were two gate contact with default schottky value is 3.5eV then, the 10_surface would be 3.5 eV Schottky barrier. but, the surface of "80" would be 3.0eV or 4.0eV (depends on the sign)
