Question

What type of semiconductor is formed when si doped with as?

Answer 1

When Si is doped with As, four electron of As forms covalent bond with the four electrons of Si while one electron remains free for conduction. N- type of semiconductor is denoted by positive ion and free electron. Therefore, n-type of semiconductor is formed when Si is doped with As or any other pentavalent atom


hope it's help you. .....❤✌❤☺❤

Answer 2

When si dropped with As .. it make n-type semiconductor.. because .. a electron of As will left ..

..hope it will help ..
