Discussion Overview

The discussion centers around the maximum size of quantum dots, exploring the limits of their size and the criteria for their classification. Participants consider theoretical and conceptual aspects of quantum dots, including their relationship to the Exciton Bohr Radius.

Discussion Character

  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants suggest there is no fundamental limit to the size of quantum dots, arguing that naming conventions are arbitrary.
  • Others propose that a quantum dot ceases to be classified as such when its size exceeds the Exciton Bohr Radius, indicating a specific threshold for nomenclature.
  • Several posts inquire whether the original question pertains to homework, reflecting concerns about forum guidelines.

Areas of Agreement / Disagreement

Participants express differing views on the existence of a fundamental size limit for quantum dots, with some asserting there is none while others emphasize the significance of the Exciton Bohr Radius. The discussion remains unresolved regarding the criteria for classification.

Contextual Notes

Participants reference the Exciton Bohr Radius as a potential threshold for defining quantum dots, but the implications of this threshold are not fully explored. The discussion also includes repeated inquiries about homework status, which may indicate uncertainty about the forum's posting rules.

What is the maximum size of a Quantum Dot? What are the limits of the size of the quantum dots? At what size do we stop calling a Quantum Dot a Quantum Dot?

Is this homework?

There is no fundamental limit, and naming schemes are always arbitrary.

no it is not homework. I think we stop naming a quantum dot a quantum dot when it exceeds the size of the Exciton Bohr Radius. The nomenclature of quantum dot had arisen when its size is in the same order as a Exciton Bohr radius. I wonder what we would call it when we reach to smaller sizes...

What would have happened if this was a homework question? I just wanted to keep in check what I could post on this website. :D

If it had been a homework question very likely this thread would have been closed and you would have been told to

1) put your question in the homework section
2) use the homework template
3) show some work

Possibly a moderator would have moved the thread to a homework section but not likely since you showed no work.

Thank you for elucidating on these details!

I'd suggest you read all of the forum rules. This is one of the few forums on the internet where they are really taken seriously.
