Doping – “The deliberate addition of impurity atom (3rd group or 5th group) element atoms into an otherwise pure Si or Ge crystal, to increase its conductivity, is called doping”. The impurity atoms are called dopants. The material that is formed after doping is called a doped semiconductor or an extrinsic semiconductor. [The dopant has … Read more
