逆向偏壓夠大時,逆向電流幾乎保持不變,稱為逆向飽和電流(reversed-biased saturation current)IS。 一般而言,pn接面二極體的電流-電壓特性可以用下式表示: 其中VT=kT/q,k為波茲曼常數,T為接面的絕對溫度,q為基本電荷大小。n稱做理想因子(idealityfactor),和二極體的種類及品質有關,通常介於1和2之間。 例題1...

If Vr is larger than a few kT/q, the total current is just the reverse saturation current (Eq. 23)I=−qA[(Dp/Lp)pn+(Dn/Ln)np] The I-V characteristic for the pn junction is shown in Fig. 6. It exhibits conduction for forward bias (V positive), negligible current for moderate ...
We know, as electrons and holes are pulled away from junction, they dont get diffused each other across the junction. So the net “diffusion current” is zero! What remains is the drift due to electric field. This reverse saturation current is the result of drifting of charge carriers from...

are continuous functions through the pn junction, the total pn junction current will be the minority carrier hole diffusion current at x = xn plus the minority carrier electron diffusion current at x = -xp.This is called an ideal diode equation (where is the reverse-saturation current density....
