4.15 A PN diode with lengths much larger than the carrier diffusion length such as shown in Fig. 4-18 is called a long-base diode. A short-base diode has lengths much shorter than the diffusion lengths, and its excess carrier concentration is similar to that shown in Fig. 8-6. A uniformly doped short-base Si diode has Nd- 101cm-3and Na 1016cm3. tp n1 us, Dp 10 cms, Dn 30 cm-s, and cross-sectional area10 cm. The length of the quasi-neutral N-type and P-type...

Problem 7: A silicon diode is asymmetrically doped at ND-10', cm? and N-1016 cm'. (Note that at N 10" the semiconductor is on the edge of degeneracy, but we can assume that non-degenerate carrier statistics are close enough for this problem.) Answer the following questions assuming room temperature. Assume that the minority electron and hole lifetimes are τ.-, 10's. The lengths of the N and P regions are L = 500 μm and 1. >> x,,x . a) Find the...
