Study on Diode. Please give some help~

[northpig87]

Hi guys,

I am in the middle of a diode lab. pretty basic stuff. There are two points I would need some extra help/resources if possible.
1. when I look at IV curve of the diode with y-axis logscaled at high current, i noticed two different slopes. I understand this is due to recombination due to the high current. Would someone give me more understanding about this recombination? (where electron and holes combine...why at high current?) any website or pdf that can be useful to help me understand this concept along with "direct process" (the non recombination process).

2. I am looking at the temperature dependence of Io and Vo of the diode. I=Io(exp(V/Vo-1.0). I see a linear relationship of Vo against Temperature and a somewhat exponential dependence of Io vs temperature, but how should I go into formulating and trying to fit the relationship?

and also, would anyone know any papers or studies done on the diode regarding these topics that I can take a look? Any help would be great!

THank you all for your help!
