The silicon sample with unit cross-sectional area shown below is in thermal equilibrium. The following information is given: T = 300 K, electronic charge = 1.6 x 10^-19C, thermal voltage = 26mV and electron mobility = 1350 cm²/V-s

The magnitude of the electron drift current density at x = 0.5 μm is
