(a) If J0 = 10.0 /xA for some p-n junction, find the current at 300 K if it is forward

biased with 0.2 V. (b) Find the current if it is

23.0 mA, -10.0 fiA. What happens to the Fermi level when the p-n junction is ...

(a) If J0 = 10.0 /xA for some p-n junction, find the current at 300 K if it is forward

biased with 0.2 V. (b) Find the current if it is

**reverse biased**with 0.2 V. Answer:23.0 mA, -10.0 fiA. What happens to the Fermi level when the p-n junction is ...

Also, let us apply a voltage across the collector-base junction such that it is

large enough to allow current to flow across the forward biased junction (from the

base ...

Also, let us apply a voltage across the collector-base junction such that it is

**reverse biased**(see Fig. 12-6). The base-emitter voltage Vj,e only needs to belarge enough to allow current to flow across the forward biased junction (from the

base ...

12-10). To see what this does to the drain-source current along the n-channel,

consider the energy diagram across the junction. In Fig. 12-11a, we show the

JFET with unbiased junctions (Va = 0). In Fig. 12-11b, we show it with
