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

Click For Summary
SUMMARY

The discussion centers on the concept of band gaps in conductors, semiconductors, and insulators. It establishes that good conductors, such as metals, do not exhibit a band gap, while semiconductors like silicon (Si) have a band gap of approximately 1.11 eV. The conversation highlights the confusion surrounding the existence of a negative band gap in semimetals, which are not classified as good conductors. Participants emphasize the need for specific numerical values and clarity in academic inquiries.

PREREQUISITES
  • Understanding of band theory in solid-state physics

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.
