At room temperature 'As' doped in Si crystal then hole density will be :-

The density of an electron-hole pair in a pure germanium is 3xx 10^(16) m^(-3) at room temperature. On doping with aluminium, the hole density increases to 4.5 xx 10^(22) m^(-3) . Now the electron density ( in m^(-3)) in doped germanium will be
