    Given,
    T = 127°C = 400°K
    μP = 800 cm2/v-s
    DP = μVT
    VT = kT/2 = 
    ⇒ DP = 800 × 0.0345 cm2/s = 27.6 cm2/s
    = -1.5 × 1022 × 10-8 × 1.6 × 10-19 × 27.6 A/cm2
    = -6.624 A/m2

    °C, the number of thermally generated electron-hole pairs increases significantly. This is due to the higher thermal energy of the atoms in the crystal lattice, which can break covalent bonds, creating electron-hole pairs. This increased number of electron-hole pairs contributes to the conductivity of the germanium semiconductor at this temperature.
