MOS Capacitor under very large positive or negative bias conditions

AI Thread Summary
In MOS capacitors, the band bending ceases when the silicon Fermi level reaches the conduction band during inversion or the valence band during accumulation. This phenomenon occurs because the energy levels align, preventing further bending. Participants in the discussion suggest utilizing Google and YouTube resources for additional insights on MOSCAP band diagrams. Despite the search for answers, some users express frustration at the lack of clear explanations. The conversation emphasizes the complexity of understanding MOS capacitor behavior under extreme bias conditions.

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)

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

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Electromagnet magnetic field issue'

Thread 'Electromagnet magnetic field issue'

Hi Guys We are a bunch a mechanical engineers trying to build a simple electromagnet. Our design is based on a very similar magnet. However, our version is about 10 times less magnetic and we are wondering why. Our coil has exactly same length, same number of layers and turns. What is possibly wrong? PIN and bracket are made of iron and are in electrical contact, exactly like the reference design. Any help will be appreciated. Thanks. edit: even same wire diameter and coil was wounded by a...

Thread 'Beauty of old electrical and measuring things, etc.'

Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
