Photoelectric effect -- direction of the electron's trajectory

Click For Summary
SUMMARY

The direction of an electron's trajectory in the photoelectric effect is not universally defined; however, in single-crystal materials with well-ordered crystal orientations, preferred directions do exist. This phenomenon is utilized in the angle-resolved photoemission spectroscopy (ARPES) technique, which allows for the analysis of electron trajectories. For further understanding, researchers should refer to relevant literature, including studies available on arXiv.

PREREQUISITES
  • Understanding of the photoelectric effect and its principles
  • Familiarity with single-crystal materials and their properties

Hi, I would like express that I really tried to dig something about the formula related to electron direction in photoelectric effect, but I could not find. Also I have seen that electron direction in photoelectric effect is not known according to some sites in internet. So, ıs it real that in which direction electron goes when photon hits the metal surface in photoelectric effect?

The direction is not defined. However, if the material is a single-crystal, i.e. the entire surface has a well-ordered crystal orientation, then there will be directions that are preferred. This is exploited in angle-resolved photoemission spectroscopy (ARPES) technique. Do a search on this and you'll see it.
