(a) What change occurs when AgCl is doped with `CdCl_(2)` ? (b) What type of semiconductor is produced when silicon is doped with boron?
(a) `CdCl_(2)` on adding to AgCl introduces impurity defect. The addition of one `Cd^(2+)` ion will replace two `Ag^(+)` ions to maintain electrical conductivity. One of the position of `Ag^(+)`...
