| Sep 22, 2016 at 19:49 | comment | added | Maxbit | Well, maybe it's because I am doing school-level physics and not university-level physics, but we can calculate the energy of that electron in the well as follows: E(n) = (n^2 * h^2) / (8*m*a^2), where a is the length of the well, m the mass of the electron, n the "level" (don't know the English term, n = 1, 2, 3....). The energy difference is deltaE=E(m)-E(n) where m is the new "level". The sufficient wavelength of the photon is then calculated by deltaE=h*(c/lambda) | |
| Sep 22, 2016 at 19:30 | comment | added | freecharly | I wonder how you can calculate the absorption of a photon by an electron in a 1-dimensional quantum well. Photons have spin 1 thus an angular momentum that has to be taken over by the electron. But the 1-d quantum well electron states do not have angular momentum. For photon absorption you have selection rules that are related to conservation of angular momentum. So how will angular momentum be conserved in your case? | |
