Question

(a) What type of semiconductor is obtained when silicon is doped with boron?
(b) What type of magnetism is shown in the following alignment of magnetic moments?
(c) What type of point defect is produced when $AgCl$ is doped with $CdC{l}_2$?

Answer 1

(a) Boron has 3 electrons in its valence shell elements with 3 electrons in their valence shell are doped with Se to produce p-type semiconductor.

(b) The diagram show ferromagnetic. ferromagnetic substances are strongly attractive by the magnetic field.

(c) When $AgCl$ is doped with $Cd{Cl}_2$, impurity defect is produced.
