The electron concentration in an n-type semiconductor is the same as hole concentration in a p-type semiconductor. An external field (electric) is applied across each of them. Compare the currents in them.
- ACurrent in n-type > current in p-type
- BNo current will flow in p-type, current will only flow in n-type
- CCurrent in n-type = current in p-type
- DCurrent in p-type > current in n-type
Solution & Step-by-step Explanation
Current is given by .Since (in n-type) = (in p-type), and the area and field are the same, the current depends on the mobility .Since electrons have higher mobility than holes (), the current in n-type semiconductor will be greater.
