Dear all,
Here I am simulating TIPS-pentacene based bottom-gate top-contact organic thin film transistor (OTFT) using Synopsys TCAD. I am using Poole-Frenkel mobility model for TIPS-pentacene OTFT simulation. For linear reion, I got similar output current characteristics in experiment as well as in simulation however, in saturation region simulated output characteristics and experimental output characteristics differs.
How to mitigate this difference? Do I need to define mobility model for saturation region?
Dear Ajay would yould you please display the simulated and measure d curves on the same graph to see how far the y are different!.
Yes the major cause for the deviation between the simulation and experimental results may be the mobility model that is deviated from the real model of mobility. I would propose that you use an empirical model for the mobility as a function of the field and temperature. The temperature of the measured curve could be different from the simulation temperature as there may be self heating of the channel. Yes the power may be very small but it is also generated in the small volume of the channel.
Yes an accurate mobility model is required to get a satisfactory fitting.
Wish you success

I am having an issue using Poole-Frenkel model in sdevice file when i run sdevice it comes up with an error of stating convergence error, but when i remove Pool-Frenkel model from the sdevice file, sdevice runs successfully,
Kindly please suggest me how to use properly the Poole-Frenkel model in sdevice file. I am using Synopsys Sentaurus TCAD
