Properties of a semiconductor:

What properties of a semiconductor are determined from a Hall effect experiment ?

Sol. The Hall Effect experiment is used to determine the following properties of semiconductors.

(i)  To determine whether semiconductor is n type or p type.

(ii)  To measure semiconductor parameter like electron or hole concentration.

(iii) To find electron or hole mobility.

(iv) To measure conductivity of material.
