Reply To: CHARGE: No change when Simulating Voltage-Dependent Transmission

[Guilin Sun]

From your description, it seems the applied voltage is not swept when you do the sweep for transmission simulation (FDTD). When you do the sweep, please select the sweep object to be the attribute, and only choose the voltage point to be the sweep parameter. You can visualize the attribute to check the max numbe of points. 

In addition, the line monitor in CHARGE has only 1D result, which might not work in FDTD, as it needs the attribute to be 2D or 3D if you simulate transmission in 2D and 3D. A 1D change of the carriers does not change the device performance since it is so small. Please make sure the attribute is applied to the proper geometry as in the real device.
