MOS Capacitor under very large positive or negative bias conditions

Click For Summary
SUMMARY

The discussion centers on the behavior of the MOS capacitor (MOSCAP) under extreme bias conditions, specifically why the energy band structure ceases to bend when the silicon Fermi level reaches the conduction band during inversion or the valence band during accumulation. Participants suggest utilizing online resources, including Google searches and YouTube videos by Jordan Edmunds, to gain further insights into MOSCAP band diagrams and related concepts.

PREREQUISITES
  • Understanding of MOS capacitor (MOSCAP) operation
  • Familiarity with semiconductor physics, particularly Fermi levels
  • Knowledge of energy band diagrams in semiconductors
  • Basic skills in conducting online research for academic resources
NEXT STEPS
  • Research the principles of MOS capacitor band bending
  • Explore the effects of bias conditions on semiconductor behavior
  • Watch educational videos on MOSCAP by Jordan Edmunds
  • Study the relationship between Fermi levels and conduction/valence bands
USEFUL FOR

Electrical engineers, semiconductor physicists, and students studying MOS capacitors and semiconductor devices will benefit from this discussion.

In MOSCAP, why does the band stop bending as soon as the Si Fermi level touches either the conduction band (inversion) or the valance band (accumulation)?

Don't know, but a Google search found some good hits.

If you watch this one directly on youtube, they show links for more videos on the subject by the same author. (Jordan Edmunds)



Cheers,

Thank you for your help. I have been searching a lot but I cannot find the answer :(
