eli5: Band-gaps, carrier electrons, electron holes

275 viewsChemistryOther

Hello!
Could someone explain electron holes to me like I’m five? Are they a concrete positive charge, or a mere absence of an electron? I have a lot of question marks in my head regarding this concept. I would appreciate resources that help to understand it too.
Thank you!

Tldr: what’s an electron hole?

An electron hole is not a real particle, it represents an empty state where an electron is supposed to be. Since you are removing a negative charge you can think of the empty state as having a positive charge.
