Question on BTE mobility average

Post by maxwhite »

Dear EPW developers:

I have some questions on the average way of mobility in EPW calculations,

I have finished IBTE mobility calculations ,take GaN results for example:

___
=============================================================================================
Temp Fermi Hole density Population SR Hole mobility
[K] [eV] [cm^-3] [h per cell] [cm^2/Vs]
=============================================================================================

100.000 11.5176 0.10000E+14 0.12925E-25 0.767956E-02 0.000000E+00 0.000000E+00
0.000000E+00 0.767956E-02 0.000000E+00
0.000000E+00 0.000000E+00 0.573540E+04
___


how should I make average on three directions ?

should I directly ( 0.767956E-02 +0.767956E-02 + 0.573540E+04)/3
to average mobility on three directions to compare with experiment results

or should I make an average in another way??


Need your help here,
thanks for you help
