what do you mean by doping?

In Sports, the athlete or players of any other games, administer drugs to enhance his/her sporting performance. They use the drug is to improve their performance. This is known as doping.

The main function of red blood cells is to carry oxygen to the muscles, and doping  results with a higher RBC count that dramatically improve an athlete’s performance by kicking up their aerobic capacity and stamina.

It is illegal and if proved, the person would get severe punishment like life ban on the sports and imprisonment etc.

 Adding suitable amount of certain impurities to intrinsic semi-conductors to increase their conductivity

 A process of addition of desirable impurity atoms to a pure semiconductor to modify its properties is termed as doping and the impurity atoms added are called dopants. For example, Silicon atom has 4 valence electrons, which bond to adjacent silicon atoms. Replacing a silicon atom with an atom that has either 3 or 5 valence electrons will therefore produce either a space with no electron (a hole) or one spare electron that can move more freely than the others. Doping leads to the creation of p-type semiconductors and n-type semiconductors.

P-type semi-conductors contain excess of holes. They are achieved by the adding group three elements (most often boron) as the dopants. These atoms contain three electrons in their valence shell.

N-type semi-conductors contain excess of electrons. They are achieved by the adding group five elements (most often phosphorus) as the dopants. These atoms contain five electrons in their valence shell.
