6. Compare the average thermal velocity of an electron, vt, at room temperature, if mv2 = 12kT, where m is the electron mass, k is Boltzmann's constant and T is the absolute temperature, with the drift velocity of an electron having a mobility of 103 cm² /volt-sec in an electric field of 1000 V/cm. The drift velocity equals the product of the mobility and the electric field. At what electric field strength will the drift velocity equal the thermal velocity? [10 marks]
