檢視 $useconstJg 的原始碼

$useconstJg is a command to switch from sweeping voltage to sweeping of current density. Note that the program is still using bias as the boundary condition, therefore, the program will spend more time in finding the current density equal to the assigned value by adjusting the bias within the range.

 $useconstJg
 type(=1) Jg -<math>\Delta</math>  +<math>\Delta</math> <math> +\Delta Vg_{min} </math> <math> J_{g} presion </math>

 $useconstJg
 type(=2) Jg_min Jg_max Jg_step -<math>\Delta</math>  +<math>\Delta</math> <math> +\Delta Vg_{min} </math> <math> J_{g} presion </math>

For example: 

  $useconstJg
  1  10.0  -0.3  0.3  1.0e-5  1.0e-4
 
This mean the program will try to current current density = 10.0 (A/cm^2). The finding range is  vgstart-0.3V to Vgstart+0.3V. It will goes to Vg in the range of 1.0e-5V. or the current density error is smaller than 1.0e-4

  $useconstJg
  2  10.0  200.0 20.0  -0.3  0.3  1.0e-5  1.0e-4

Note: Using $useconstJg, the command of Vgend and Vgstep will be disable. The program will only start from vgstart.
