MoS2 based Transistor

Please login with a confirmed email address before reporting spam

To the COMSOL Community and Experts,

I am writing to request assistance with a convergence issue I am encountering while using the COMSOL Semiconductor Module.

My objective is to replicate a simulation based on a publicly available model of an MoS2 + HfO2 transistor (which I will refer to as the "2nd file"). I have constructed my own project, "MoS2_transistor" (the "1st file"), by carefully transferring the physics, parameters, and mesh settings from the reference model.

A critical problem has arisen: while the reference model (2nd file) computes and converges successfully, my implementation (1st file) consistently fails to converge and terminates with an error.

Given that the reference file functions correctly, I suspect there may be a subtle discrepancy or setup error in my project file that I am overlooking.

I would be extremely grateful if an expert could offer guidance or insights to help diagnose and resolve this convergence failure.

Thank you for your time and consideration.

Sincerely,
