Do quantum dots always have to be semiconductors?

Click For Summary
SUMMARY

The discussion centers on the nature of quantum dots, specifically questioning whether they must always be semiconductors. Participants explore the existence of insulator and conductor quantum dots, detailing their respective band structures. Insulator quantum dots exhibit a band gap that prevents electron flow, while conductor quantum dots allow for free electron movement. These differences significantly impact the absorption and emission characteristics of light in these materials.
