Question: problem 2 a 1 cm long wire of 1 mm2...

Question details

Problem 2: A 1 cm long wire of 1 mm2 cross section is placed in an electric field of 1 V/cm. Suppose that the mean time between scattering events is 1 psec (10-12 sec). If the carrier concentrations are: 1x105 cm-3 (a good insulator) ii 1x1015 cm (a weakly conductive semiconductor) iii. 1x1018 cm -3 (a highly conductive semiconductor) iv. x1023 cm3 (a highly conductive metal) A. Calculate the current in the wire for each material. B. Calculate the velocity of the carriers in each material.
