Question:
A uniform bar of n - type silicon of 2 micro m length has a voltage of 1 V applied across it.If Nd = 10^16 /cm^3 and miu n ( electron mobility) = 1350 cm^2/V.s,
(a) find the electron drift velocity
(b) the time it takes tg electron to cross the 2 micro m length
(c) the drift current density and
(d) the drift current in the case the silicon bar has a cross sectional area of 0.25 micro m^2.
