Analysis Flow

Similar to most subjects, the analysis of semiconductor devices is also performed by starting from simpler problems and regularly progressing to more complex ones as explained below:

1. Analysis under zero excitation that is equilibrium.
2. Analysis within constant excitation: in other words dc or static characteristics.
3. Analysis within time varying excitation but with quasi-static approximation dynamic characteristics.
4. Analysis within time varying excitation: non quasi-static dynamic characteristics.

   

Although there is zero external current and voltage in equilibrium, the condition inside the device is not so trivial. Generally, voltages, charges and drift-diffusion current components at any specific point within the semiconductor might not be zero.
