Problem: An electron is trapped in a "quantum well" that confines it to a narrow region in one dimension. The electron's minimum energy is 0.19 meV. What's the width of the well?

FREE Expert Solution

The width of a well and the energy are related by:

En=h2n28ma2

a is the width of the well.

Take the first energy level, n = 1
