1. Calculate the intrinsic carrier concentration in germanium at 300 K. Given that me *=1.09 m0, mh *=0.31 m0 and Eg = 0.68 eV. Given T = 300 K, k=1.38×10-23 Jk-1, h=6.626×10-34 Js, m0 = 9.11×10-31 Kg, Eg = 0.68 eV = 0.68×1.6×10-19 J, me *=1.09 m0 = 9.929×10-31 Kg, mp* = 0.31 m0 =

1. A uniform silver wire has a resistivity of 1.54 × 10-8 Ωm at room temperature, for an electrical field along the wire of 1 V/cm. Compute the drift velocity of electron assuming the there are 5.8 × 1028 Conducting electrons/m³. Also calculate the mobility. Given ρ = 1.54 × 10-8 Ωm, E = 1
