rangeN: How many regions in the simulation domain that we need to consider memory effect <br>
TraploopN: How many sweeping we would like to perform<br>
V_bias_type: 4: drain bias  21: gate bias <br>
Trap_decay_type: The model we want to apply in the simulation. It decides how the traped charges change with time<br>
<br>
For Trap_decay_type=1, the trapped charge in first sweep will be totally saved in the simulation for the next sweeps. The trapped charge will not decay.

For Traptype=12 each region has the same decay_lifetime(s). The trapped charge will decay as time going. If no more trapped coming in, the saved trapped charge will go to zero as time going
