AI Thread Summary
The discussion centers on understanding the formula related to negative charge density (ni) in intrinsic materials. Recommended resources include "Semiconductor Fundamentals" by Pierret, which provides a readable introduction and relevant equations. For more advanced insights, Kittel's "Solid State Physics" offers deeper treatments, particularly in chapter 8. Participants emphasize the importance of consulting semiconductor device literature for comprehensive explanations. These resources are essential for developing a solid understanding of the topic.

i know that ni is the negative charge density in the intrinsic material

Many books on semiconductor devices will likely have some sort of discussion leading up to this equation. One nice example is is the little paperback book
"Semiconductor Fundamentals", by Pierret. This is Volume I of a series on solid state devices and it is quite readable. The equation is a combination of equations 2.21, 2.13a and 2.13b from that book.

Deeper treatments can be found in books on solid state / semiconductor physics. For example, chapter 8 of Kittel's "Solid State Physics" covers this.

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...
