$solvetimestep2D is a command for solving the transient behavior of the device. The format is
$solvetimestep2D number_of_different_steps(Nt) steptype contact_typepar1 par2 par3 par4 .... steptype contact_type
The number of parameters depeding on step type. Now we have 3 step types
Steptype = 1:
for t<0, for t>0, vg=
Steptype = 2:
Steptype = 3:
contact_type
2: gate 3: source 4: drain
Steptype = 4:
, generation = system generation at t<0 and generation =0 for t> 0
Steptype = 5:
Steptype = 6:
Steptype = 7:
Steptype = 8:
For example:
$solvetimestep2D 2 2 2 1.0e-10 1.0e-6 3.00 0.1 1.0e6 0.0 2 4 1.0e-10 1.0e-6 3.00 0.1 1.0e6 0.0
The $Solvetimestep2D setting in GUI interface is here
1. Press Time Dependent module, check the box and press Add new sweep modes.
2. Fill in the fields as needed!
