Delat energy required to excite hole from lowest energy orbit to valence band?

Click For Summary
SUMMARY

The discussion centers on calculating the delta energy (\delta\epsilon) required to excite a hole from its lowest energy orbit to the valence band. The concept of holes is clarified as a mathematical construct rather than a physical entity. Participants express confusion regarding the terminology used, particularly the reference to "orbits" in the context of holes.

PREREQUISITES
  • Understanding of semiconductor physics
  • Familiarity with energy bands in solids
  • Knowledge of quantum mechanics principles
  • Basic concepts of hole theory in solid-state physics
NEXT STEPS
  • Research the concept of energy bands in semiconductors
  • Study the mathematical modeling of holes in solid-state physics
  • Learn about excitons and their relation to holes
  • Explore quantum mechanics applications in semiconductor theory
USEFUL FOR

Students and professionals in physics, particularly those focusing on semiconductor technology, as well as researchers interested in solid-state physics concepts.

Delta energy required to excite hole from lowest energy orbit to valence band?

I have calculated the orbit of a hole in its lowest energy orbit, but am struggling to work out \delta\epsilon (energy needed to excite it to valence band).

Any help much appreciated.

"the orbit of a hole in its lowest energy orbit"

what do you mean by that?

1) Holes are just a conceptual construct that help us do the math easier. Holes do not exist.

2) What do you mean by the orbits?
