Electrons in periodic potentials -- lesson

[plp81]

Hi, I need to teach a lesson on electrons in periodic potentials for Bachelor Physics students in just 20 minutes

Any ideas on how to organize the lesson (pre-concepts they should know, relevant message and consequences) would be very much appreciated

Hello plp,

There should be something of a context for these students - you can't expect PF help on that.

As a former student and not knowing much about the field, I might contribute my expectations in such a situation:

From energy levels in a single well to periodic goes via double well and leads to band structures. If you can bring that off in 20 min, you're a hero for me !

Thank you BvU

Indeed that is a logical sequence, thanks! I might not include the double well and go directly to periodic potential. I was asked to do this for job interview so i'll need to become a hero!

Best of luck !

I'm actually curious on how this went :P
