Electrons in periodic potentials -- lesson

Click For Summary

Discussion Overview

The discussion centers around organizing a lesson on electrons in periodic potentials for Bachelor Physics students. It includes considerations for pre-concepts, relevant messages, and the implications of the topic within a limited time frame.

Discussion Character

  • Homework-related, Conceptual clarification

Main Points Raised

  • One participant suggests that a context is necessary for students to understand the topic, proposing a logical sequence from energy levels in a single well to periodic potentials, potentially including double wells and band structures.
  • Another participant expresses a desire to focus directly on periodic potentials, indicating a preference to streamline the lesson for the time constraints of a job interview.
  • There is an expression of encouragement and curiosity regarding the outcome of the lesson preparation.

Areas of Agreement / Disagreement

Participants generally agree on the need for a logical sequence in teaching the topic, but there is a divergence regarding whether to include the double well concept or focus solely on periodic potentials.

Contextual Notes

Limitations include the time constraint of 20 minutes and the potential need for foundational knowledge that students should possess before the lesson.

Who May Find This Useful

Educators and students interested in teaching or learning about quantum mechanics, specifically the behavior of electrons in periodic potentials.

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, :welcome:

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
