Silvaco IC simulation with Athena Atlas

Click For Summary

Discussion Overview

The discussion revolves around issues and questions related to the Silvaco Athena and Atlas simulation tools, specifically in the context of MOS structures, PIN solar cells, tunneling effects in junctionless devices, and the simulation of solar cells using GaAsN alloy. Participants seek assistance with error messages, unexpected simulation results, and specific modeling techniques.

Discussion Character

  • Technical explanation
  • Debate/contested
  • Homework-related

Main Points Raised

  • One participant reports an unexpected decrease in threshold voltage (Vth) when reducing the gate length in a MOS structure simulation, questioning the accuracy of the program.
  • Another participant encounters an error message regarding a missing file while simulating a PIN solar cell and seeks guidance on including external files for spectral absorption coefficients.
  • A question is posed about implementing "Non local band to band" tunneling in Silvaco Atlas for a junctionless device, indicating a need for specific modeling techniques.
  • A participant describes a simulation issue with a solar cell using GaAsN alloy, where increasing the number of quantum wells leads to a decrease in efficiency, prompting requests for insights.

Areas of Agreement / Disagreement

Participants express various technical challenges and seek solutions, but there is no consensus on the causes of the issues or the methods to resolve them. Multiple competing views and approaches are present.

Contextual Notes

Limitations include potential missing assumptions in the simulations, dependencies on specific definitions or configurations within the Silvaco tools, and unresolved technical steps related to the implementation of certain features.

I have a question about silvaco athena && atlas simulation, MOS structure, when I gate length is 0.6um, get Vth is 1.8V, but I only change gate length to 0.55um, get Vth is 1.6V, it's a error data I know, but I do not know why, what wrong with the program, how can I change it. would you please help about it. Very thanks!

Hi, i have problem with Silvaco please. when i simulate an PIN solar cell by atlas, an error message appear and say The atlas Silvaco could not open the file called "Solarx01.spec", i know no where is the problem realy! another question: how we can include an external files (.txt) who contains for example the spectral absorption coeficient or the reflexion in the atlas. Thanks
 
How to apply "Non local band to band" tunneling in Silvaco Atlas for a junctionless device?
 
hi ,i need help
i simulate a program in silvaco about solar cell with GaAsN alloy and i have a problem
in my program i need that the efficiency when i increase the numbre of the quantum well it should increase to but in my case it decreases
if you have any idea please help me
