What is the value of the band gap in a good conductor

Click For Summary

Discussion Overview

The discussion revolves around the value of the band gap in good conductors, exploring the distinctions between conductors, semiconductors, and insulators. Participants express uncertainty regarding specific energy gap values and the nature of band gaps in different materials.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Homework-related

Main Points Raised

  • Some participants question the definition of a band gap and the differences between conductors, semiconductors, and insulators.
  • One participant notes that conductors can overlap, raising the question of whether a gap exists at all.
  • Another participant claims that there is no gap in good conductors, suggesting that a negative value might be considered, but expresses confusion over the instructor's expectations for specific numbers.
  • A later reply states that good conductors do not have gaps or anything resembling a negative gap, while semimetals might be described as having a negative gap but are not typically classified as good conductors.
  • One participant indicates that they will seek clarification from their instructor regarding the requirements for their assignment.
  • Another participant critiques the vagueness of the original question and suggests that it should have been posted in a different forum dedicated to homework or coursework.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the existence or value of a band gap in good conductors, with multiple competing views expressed throughout the discussion.

Contextual Notes

The discussion highlights limitations in the clarity of the original question and the need for specific definitions and context when discussing band gaps in different types of materials.

sorry i moved it to correct forum i rushed in, in my panic

I can be completely off, but... think: what is a band gap? What is a difference between conductor, semiconductor and isolator?
 
The difference between conductor, semiconductor and isolator is the size of the gap the smaller the better the conductivity conducters can overlap but unfortunately i need specific numbers of the energy gap value like Si =1.11eV but i need the value of a good conductor not a semiconductor.

conducters can overlap

If they do, is there a gap at all?
 
there is no gap but there is still a value it will be a negitive value my lecture wasnt happy with my explanation of there being 0 value he wants specific numbers
 
I don't know what your instructor is looking for.. good conductors don't have gaps, or anything that resembles a negative gap. Semimetals can be described as having a negative gap, but they aren't usually good conductors.
 
Ok guys thanks for all the rapid response mucha grazsia i will email my teach now and find out what he wants as it has to be handed in on monday (Arrgggh)
I will update this thread with what his replie is for those that are interested.
Thanks all PF members.
 
It appears that this is a school work and should have been done in the HW/Coursework forum. Furthermore, your question is utterly vague (if you noticed, several posts here were addressing a very confusing part of your question, not addressing the possible answer).

If you are asking something as part of a school work, do that in the HW/Coursework forum. Per the rules of that forum, post the whole, complete question, not just your interpretation of the question.
