I was looking for a "nearly free electron model". I enjoyed the script.

The distance 0 to L would be like a side length of the sample of atoms you have. So if you had a crystal of silicon you could take a ruler and measure L by hand.

Great videos, they are really helpful. I'm taking Solid State Physics now and am studying the free electron model. One thing I don't understand is what is the relationship between the 1D line where the electrons are accomodated (as Kittel puts it) and the atomic lattice. Is the 0 to L distance the space between atoms? Or is 0 to L a line of atoms with electrons free to move in this line?

can you guyz please explain what are mott Insulators....I couldn't find any satisfacory explanation for same. There are still question to me like how electron - electron interaction occur and how mott resolved it.??

Sagar Rawal Electron-electron interactions are always there, and they repulse each other via Coulomb interaction, which can impede electrons from hoping from site to site if strong enough, leading the material to enter the so-called “Mott insulator” phase.
