Carrier velocity and conductivity. A power device is made of silicon and carries a current of 100 A The size of the device is 10 mm x 10 mm and is 1 mm thick. The potential drop on the device is 0.6 V.
(a) What is the conductivity of the silicon used.
(b) If the velocity of the carriers is 2000 m/s, how many free charges (electrons) must be present in the device at all times?
