Dear Abdullah
Yes you can calculate indirectly all this parameter's by using Boltztrap
code.
Boltztrap give you as output file ( carrier concentration,
conductivity/carrier lifetime)
so by using this equation [1] you can calculate carrier lifetime
[1]:K.P.Ong, D.J.Singh, P.Wu, Phys. Rev. B 83 (2011) 115110.
carrier lifetime=2.53*(10^-5)*(T^-1)*(n^(-1/3)) [1]
were T:temperatur, n: carrier concentration.
and if u want calculate mobility use this equation :
mobility=conductivity/(charge elementaire*carrier concentration)
i think if you have this parameters you can calculate diffusion length.
