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