$solvetimestep is a command for solving the transient behavior of the device. The format is
$solvetimestep number_of_different_steps(Nt) steptypepar1 par2 par3 par4 .... steptype
The number of parameters depeding on step type. Now we have 3 step types
Steptype = 1:
vg=vg_end for t<0, for t>0, vg=
Steptype = 2:
Steptype = 3:
For example:
$solvetimestep 2 2 1.0e-10 1.0e-6 3.00 0.1 1.0e6 0.0 1 1.0e-10 1.0e-6 3.20 first run
then run
The $solvetimestep setting for 1D-DDCC in GUI interface
3.Modify the number of layers.
4.Choose the steptype.
5.Modify the parameters.
