Problem: A 2 cm long piece of Si with cross-sectional area of 0.1 cm2 is doped with donors of 1015 cm3, and has resistance of 90 ohms. The saturation velocity of electrons in Si is 107 cm/s for fields about 105 V/cm.

Part A: Calculate the electron drift velocity, if we apply a voltage of 100V across the piece?

Part B: What is the current through the piece if we apply a voltage of 106 V across it?

Please show all work and steps to determine the electron drift velocity.
