Doping of semiconductors



n doping This involves substituting Si by neighboring elements that contribute excess electrons. For example, small amounts of P or As can substitute Si.
Since P/As have 5 valence electrons, they behave like Si plus an extra electron. This extra electron contributes to electrical conductivity, and with a sufficiently
large number of such dopant atoms, the material can displays metallic conductivity. With smaller amounts, one has extrinsic ....etc

1.1:INTRODUCTION
All of us know how importance of using materials like copper , aluminium etc. in electrical applications. This is because copper aluminum are good conductors. Similarly some materials like glass, wood, paper etc also find wide applications in electrical and electronic applications, these are called insulators. There is also another category of materials whose ability to carry current call ....etc
