How Is the Thickness of a Quantum Well Determined?

Thickness of Quantum Well ??

As I know there are two quantum wells exist.

1. Single Quantum Well
2. Multiple Quantum Well

My ques is that : How to find the thickness of a quantum well ? is there any equation to find quantum well thickness ? for single or multiple ?

Usually I have look on papers they just simply put the thickness they have used in their modeling and experimental but not given from where they got it.

Thanks in advance.
