$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)
