Classify each of the following as being either a p-type or a n-type semiconductor : (i) Ge doped with In (ii) B doped with Si. |
|
Answer» Solution :(i) p-type SEMICONDUCTOR, because group 14 element is doped with group 13 element. An electron DEFICIT hole is CREATED. (ii) n-type semiconductor, BEAUSE group 13 element is doped with group 14 element. A free electron will become available. In general, an element doped with an element of the following group produces n-type semiconductor while an element doped with an element of the previous group creates a p-type semiconductor. |
