<div dir="ltr"><div><div><div><div><div>Dear All users,<br></div>There are various tou (tauref,
tauexp, taurefen, tempexp, taureftemp) parameters used in the
case.intrans file for doing the boltztrap calculation. How and what are
the values one can set for these parameters. In the reference Durczewski
et al. PRB 61 5303 (2000) it is suggested that the value of tauexp
(scattering constant parameter r ) should not exceed the value 4. Is
there any way to select the values of various tou in boltztrap
calculation for the interested thermoelectric materials, and if any then
what is the range or max limit ??? I am doing the calculation for
ZnV2O4 compound by using the touexp value 26, with this touexp value it
gives the thermopower value well matching with experimental value in
300-600 K temperature range. It is my request to suggest me the method
orĀ expression by which one can choose the tou value which make the
physical sense with the interesting compound calculations. You can also
suggest some articles or books which gives the details of relaxation
time dependent thermoelectric behaviour in high temperature range. i
will be highly thankful for you reply. Looking for a positive response
very soon.<br><br></div>Thanks a lot.<br><br><br></div>-Regards<br></div>Saurabh Singh<br></div>IIT Mandi<br></div>
