carrier mobility

Post by wangshaofei18 »

hello
I am calculate the intrinsic carrier mobility
when I set:
carrier = .true.
ncarrier = 1E17
and calculate the carrier mobility at high temperatures of 300~800
at a high temperature, the electron/hole concentration is not 1E17 it exceeds to 1E21.
800.000 10.2780 0.333531E+21 0.440075E+01 x-axis
but when we set the carrier mobility is 1E20, we got the mobility
800.000 9.7980 0.999991E+20 0.172406E+03 x-axis
that makes our mobility lower at the low carrier concentration, and this is not the right outcome.
I want to get the carrier mobility at 1E17 and compare the effect of carrier concentration on carrier mobility.
Is there any way to fix the problems?
