Discussion Overview

The discussion explores the potential effects of cosmic rays on the conductive properties of graphene, particularly in the context of outer space. Participants consider the implications of defects introduced by cosmic rays on graphene's conductivity.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant questions whether graphene can retain its conductive properties after exposure to cosmic rays, noting that its conductivity arises from free electrons in its carbon structure.
  • Another participant suggests that cosmic rays would introduce defects in graphene over time, though the timeline for how quickly this would affect conductivity is uncertain.
  • A further inquiry is made about the specific ways in which defects might influence graphene's conductivity.
  • One participant raises a question about whether any materials on Earth experience similar effects from cosmic rays.

Areas of Agreement / Disagreement

Participants express uncertainty regarding the timeline and mechanisms by which cosmic rays might affect graphene's conductivity, indicating that multiple views and questions remain unresolved.

Contextual Notes

The discussion does not clarify the specific types of defects that may arise or their precise impact on conductivity, leaving these aspects open to interpretation.

I had a random idea and wanted to know whether graphene could retain it's conductive properties after being exposed to cosmic rays.

I know that graphene gets it's conductivity from the free electrons from its carbon atoms.
I know that cosmic rays consist mainly of protons, with the minority being heavier positive nuclei, traveling near the speed of light at energies of around 1 GeV/c.

Would this affect graphene's conductive property in any way?
 
Physics news on Phys.org
Cosmic rays would introduce defects in graphene (and any other solid material) over time. I don't know how quickly that would influence the conductivity.
 
How exactly would defects affect graphene's conductivity?
 
Anything here in the Earth feel the cosmic ray effects
