प्रश्न
A perfect crystal of silicon (Figure) is doped with some elements as given in the options. Which of these options show n-type semiconductors?
उत्तर
Explanation:
When group 15 elements are doped into a perfect crystal, it leads to the formation of n-type semiconductor. Here, in as (group 15, period 3) is doped to perfect Si-crystal and in as (group 15, period 2) is doped to perfect Si-crystal.
