Question: 72 2 which one eq for ntype and ptype semiconductor...

Question details

△72 2 Which one eq. for n-type and p-type semiconductor? Why are these called diffusion equations? Why are these called minority carrier diffusion equations? Why these eqs. valid under lower-injection condition? Consider n-type Si sample at 300 K doped Np-1014 cm-3. The end of the sample is irradiated with light as shown, such that Δ 0-1010 cm -3 at x-0. No light penetrates inside Si (x>0). Determine Ap,(r). (page 129 pierret book) ˇ热点新闻 Table 3.1 Common Diffusion Equation Simplifications. Effect
