Discussion Overview

The discussion revolves around experimental methods to demonstrate the conductivity of semiconductor materials. Participants explore various techniques and phenomena related to semiconductor behavior, including temperature effects and the Hall effect.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested, Experimental/applied

Main Points Raised

  • One participant suggests conducting experiments related to temperature versus resistivity and tunneling spectroscopy.
  • Another participant proposes that applying a temperature gradient could generate a potential, indicating a property of semiconductors.
  • The Hall effect is mentioned as an interesting phenomenon relevant to the discussion.
  • Some participants note that conductors also exhibit the Hall effect, with one clarifying that metals are typically referred to as conductors.
  • A later reply discusses the differences in Hall effect measurements between metals and semiconductors, emphasizing that temperature-dependent measurements reveal distinct behaviors and that Hall voltage is generally lower in metals.

Areas of Agreement / Disagreement

Participants present multiple viewpoints regarding the experimental methods and the implications of the Hall effect, indicating that the discussion remains unresolved with competing perspectives on the topic.

Contextual Notes

There are limitations regarding the assumptions made about the definitions of conductors and semiconductors, as well as the specific conditions under which the Hall effect is measured.

hi
which expermient we should do to proof that a material's semiconductor??
thanks for replying
 
Physics news on Phys.org
Temperature versus resistivity, tunneling spectroscopy, etc... etc.

Zz.
 
if you apply a temperature gradient it should generate a potential.
 
Hall effect is pretty cool
 
Conductors also show the Hall effect.

i guess a metal is meant by conductor.

you' re right, metals also show hall effect but temperature dependent Hall effect measurements (e.g. between 20K and 800K) show the different behaviour of metals and semiconductors. In addition, the Hall voltage is typically much lower in metals.
