Is it possible to simulate a-IGZO and LTPS thin film transistors using Sentaurus?

Does Sentaurus TCAD have the material model for aIGZO and poly-Si inbuilt (or found in some other resource)? Is it possible to simulate aIGZO and poly-Si based TFT using channel material...

Why are the 16 parasitic capacitances (Cgg, Cgd, Cgs, Cgb, Cdd, Cdg, Cds, Cdb, etc.) found through AC analysis in TCAD (Sentaurus) and Spice are diff?

The intrinsic capacitances in a MOSFET can be simulated using TCAD's ac analysis solve statement. There are 16 total capacitances as provided in this link:...

In MOSFET, the capacitance is related to voltage through the formula C=dQ/dV. Is this voltage (dV) across the capacitor or between electrode and gnd?

In MOSFET small signal analysis, we can relate charge (Q) and capacitance (C) using the formula Cij = dQi/dVj. Is the voltage term (dVj) calculated across the electrode terminals 'i' and 'j' ? Or...

For calculating Qg, Qb, Qd, Qs of a MOSFET (in Genius TCAD), should we DC bias gate and drain and AC input (small signal analysis) at each electrode?

We can calculate Q from capacitance as Cij = dQi/dVij. When I input an ac signal through Gate electrode while the MOSFET is DC biased at gate and drain (source and body are grounded), I get Cbg,...

Why use MoOx/Ag instead of MoOx/Au in inverted organic solar cells?

May I know why most literature, including yours, use ITO/ETL/P3HT:PCBM/MoOx/Ag configuration instead of .../MoOx/Au configuration? Does MoOx/Ag have any workfunction advantage over MoOx/Au (Since...

How do I use AM1.5 as optical source instead of C interpreter in Silvaco Atlas example solarex07.in? Also how do I use PHOTOGEN statement?

I want to do optical modelling with P3HT:PCBM solar cells. So how do I use AM1.5 optical source instead of the C interpreter in solarex07.in example? If I replace the C interpreter with...
