A10mm cube of germanium passes a current of 6.4ma when 10mv is applied between two of its parallel faces. assuming that the charge carriers are electrons that have a mobility of 0.39m^2 v^–1 s^–1 , calculate the density of carriers. what is their collision time if the electron’s effective mass ingermanium is 0.12 m_0 where m_0 is the free electron mass?
