Can anyone explain the Aharonov Bohm effect in quantum dots?

[ordinary_girl]

can anyone explain to me what is Aharonov Bohm? I read it in wikipedia but I'm still blur
How can we see this effect in quantum dots?

For example: GaSb quantum dot in GaAs (holes strongly confined in GaSb, electron is loosely bound due to Coulomb interaction)

Any help/explanation/correction is highly appreciated.

I wish I could help but I have never heard of that before.
