Question

If the p-side has a higher doping concentration, explain how to keep tuning to the same radio channel?

Answer 1

Answer:

increase in temperature of the intrinsic semiconductor

Explanation:

• If the p-side has a higher doping concentration, it implies that number of holes (positive ion) increased which is greater than number of electron (negative ion) in the n-side
• in order to balance the intrinsic concentration, that is to balance the number of holes and electrons which depends on temperature.
• an increase in the temperature of the intrinsic semiconductor (p-side), increases the number of electron but number of holes remains constant.

A balance in the intrinsic concentration helps in tuning to the same radio channel.
