When the system has ion to perform as drift-diffusion equations, we solve the time dependent drift-diffusion for slow ion move simulation. Since the ion moves may not be governed fermi-level concept. We simply treat is a tradiational drift-diffusion equations.
Ideally, the ion density is given by initial setting. The total ion number should be fixed. The program is aim to model multi-ions drift-diffusion. The command is as following.
$Withionmove Sweep_type_1 P1 P2 P3 P4 P5 ... Sweep_type_1 P1 P2 P3 P4 P5 .. ... ... Sweep_type_N_{sweep P1 P2 P3 P4 P5 .. p3 p4 Parameters of the 1 layer p3 p4 Parameters of the 2 layer p3 p4 Parameters of the 3 layer .... ..... p3 p4 Parameters of the $totalregion layer
: The number of runs for the time step : The number of output results for each run Sweep_type: 1: constant voltage, P1 to P5 is not used 2: Sweep Vg during this time period P1=Vgstart, P2=Vgend, P3=swdt of each step (step Number= 3: Sweep Vd during this time period P1=Vdstart, P2=Vdend, P3=swdt of each step 4,5,6.... leave for future use : The time for the first run. The time for the 2nd run. is the for each sweep. How many ions are considered. If we only want to consider 1 negative ion,we can put 1 The sign of ions. only accept
For example: Consider 2 ions, 1st is negative charges, 2nd is positive charges, total 5 Regions we can

is the parameter type: it depends on ion number 1: , ,........ 2: , ,........
When type 1 is chosen, we only put mobility , and the diffusion coefficient is calculated with Einstein relation, where
