An electron is bound in a square well of depthU0=6E1−IDW.
What is the width of the well if its ground-state energy is 2.50 eV ?
En = h2n2/8mL2
The Attempt at a Solution
I used n = 1
so I get:
25eV*1.6*10-19 = h2/8*9.11*10-31*L2
I got L = .388 nm. It wasn't correct. I ignored the depth part at the beginning since I thought it was irrelevant, but it might not be
