Discussion Overview

The discussion revolves around a homework question regarding the tunneling current as a probe passes over an atom that is 3.20×10^2 nm tall. Participants explore concepts related to quantum tunneling and its implications in this context.

Discussion Character

  • Homework-related, Conceptual clarification

Main Points Raised

  • One participant asks about the factor by which the tunneling current increases when a probe passes over an atom of a specified height.
  • Another participant questions whether the inquiry is related to homework and prompts for prior knowledge about tunneling.
  • A participant confirms that the question is indeed homework and requests a hint.
  • One participant claims to have figured out the problem, though no details are provided.
  • Another participant reiterates the homework nature of the question and suggests that such inquiries should be posted in a dedicated homework forum, questioning the rationale behind the existence of the forum.

Areas of Agreement / Disagreement

Participants generally agree that the question pertains to homework, but there is no consensus on the specifics of the tunneling current or the appropriateness of the forum for such questions.

Contextual Notes

The discussion does not clarify the assumptions or definitions related to tunneling current, nor does it resolve the mathematical steps necessary to answer the original question.

The probe passes over an atom that is 3.20×10^2 nm "tall."

The probe passes over an atom that is 3.20×10^2 nm "tall." By what factor does the tunneling current increase?

Is this your homework? What have you learned about tunneling?
 


Yes this is my homework, can you give me a hint
 


I figure it out :)

please post homework in the homework forum. why do you think there exists such?
