1,

A wafer of intrinsic silicon is deliberately doped with 3 X 10^20/m^-3 of acceptor atoms

1, CAlculate the electron and hole concntration in the wafer

2,calc the position of the Fermi level in the band-gap

3calculate the conductivity of the wafer

Constants

q = 1.6 X 10^-19C,k = 1.38 X 10^-23J/K = 8.6 X 10^-5eV/K,ni = 1.45 X 10^16m-3,Nc= 2.5 X 10^25m^-3,EG(Si)= 1.1eV...

Thanks a lot in advance for your assiatance
