EXERCISE 3.4 A uniform bar of n-type silicon of 2-um length has a voltage of I V applied across it. If N, = 10"/cm' and a,- 1350 cm'/V-s, find (a) the electron drift velocity, (b) the time it takes an electron to cross the 2-um length, (c) the drift-current density, and (d) the drift current in the case that the silicon bar has a cross-sectional area of 0.25 um'. Ans. 6.75 x 10 cm/s 30 ps; 1.08 x 1o' Alem: 27 uA 3.3.2 Diffusion Current
