A n-type piece of silicon with a length of 0:1 μm and a cross section area of 0:05μm × m0:05 μm sustains a voltage difference of 1 V.
(a) If the doping level is 1017 cm3, calculate the total current flowing through the device at T = 300 K.
(b) Repeat (a) for T = 400 K assuming for simplicity that mobility does not change with temperature. (This is not a good assumption.)
