I'm wondering how this actually can be solved since i think there is one piece missing.
Determin the diffusion length L on a P+N diode with Nd = 10^16 cm^-3 in the N region.
Known is that Diffusion length can be found from L=sqrt(Dt)
As D = kT/q*u where u can be determined using a electron and hole mobility graph.
But now how can i find t?
It is not staded what t is.
