Question
Classify each of the following as being either a p-type or a n-type semiconductor:
- Ge doped with In
- B doped with Si
Advertisements
Solution 1
| p-type semiconductor | n-type semiconductor |
| Ge doped with | B doped with Si |
Solution 2
- While In is a group 13 element, Ge is a group 14 element. When Ge is doped with In, the doped material will behave as a p-type semiconductor and electron-deficient holes will be formed in the lattice.
- Si is an element in group 14, whereas B is an element in group 13. The doped material will function as an n-type semiconductor and conduct electricity using the standard electron conduction method.
