When a p-type semiconductor material is bonded to an ntype

Home » Electrical Engineering materials » Electrical engineering material miscellaneous » Question

When a p-type semiconductor material is bonded to an ntype semiconductor material and terminals are added the resulting structure has the property that:

1. a built in potential results
2. a voltage appears at the terminals
3. resistance increases with increasing temperature
4. a good conductor results since both n and p materials are doped

Correct Option: A

When a p-type semiconductor material is bonded to an n-type semiconductor material and terminals are added, the resulting structure has the property that a built in potential results.
