SUMMARY

Holes in semiconductors are defined as sites of missing electrons within the solid structure, leading to the movement of charge carriers. When a potential difference is applied, electrons fill these holes, causing the holes to effectively move in the opposite direction, contributing to electric current. Holes are classified as positively charged entities, despite not being actual particles, as they represent the absence of negatively charged electrons.

PREREQUISITES
  • Understanding of semiconductor physics

I understand that holes are sites of missing electrons in the structure of a solid semiconductor. When there is a potential difference between the ends of a sample, electrons can move to fill the holes and in effect the holes move the other way to form an electric current.

However, is the hole positive or negative charged?

hole is regarded as positive charged. But holes just "lack" of electrons, they are not real particles.
