प्रश्न
Give reasons : Silicon on doping with Phosphorous forms n-type semiconductor.
Advertisements
उत्तर
Phosphorus is electron rich as it is element of group 15. When it is doped with element of group 14 i.e silicon an n-type semiconductor will form because here conductivity is due to the presence of extra electrons.
