(i) Ge (a group 14 element) is doped with In (a group 13 element). Therefore, a hole will be created and the semiconductor generated will be a p-type semiconductor.

 (ii) B (a group 13 element) is doped with Si (a group 14 element). So, there will be an extra electron and the semiconductor generated will be an n-type semiconductor.

Classify each of the following as either a p-type or n-type semi-conductor

Hint : (a) Ge is group 14 element and In is group 13 element. Therefore, an electron deficit hole is created. Thus semiconductor is p-type.  (b) Since B is group 13 element...

A group 14 element is to be converted into n-type semiconductor by doping it with a suitable impurity. To which group should this impurity belong?

An n-type semiconductor conducts because of the presence of extra electrons. Therefore, a group 14 element can be converted to n-type semiconductor by doping it with a group 15 element.

During a sale, colour pencils were being sold in packs of 24 each and crayons in packs of 32 each.

Number of color pencils in one pack = 24 No of crayons in pack = 32 ∴ The least number of both colours to be purchased = LCM of 24 and 32 = 2...
