Dear researchers£º<br>Hello, everyone. Let me ask you a question about EPW.<br><div>First£¬this is the pw, EPW version and phonon version I use£º</div><div><br></div><div>Program PWSCF v.6.8 starts on 19Oct2021 at 10:47:42 <br></div><div>Program EPW v.5.4 starts on 19Oct2021 at 10:41:49</div><div>Program PHONON v.6.8 starts on 19Oct2021 at 10:42:21 <br></div><div><br></div><div><br></div><div>Now,
When I calculated the hall mobility with EPW software, I normally got
the output epw.out file, but I was confused about the reading of hall
factor and Hall mobility matrix:<br>The diagonal values of hall factor and mobility matrix are too far off the mark, but the value <span style="color: rgb(255, 0, 0);">r</span><font size="1"><span style="color: rgb(255, 0, 0);">21</span></font>£¨0.103271E+01£© on a non-diagonal line meets our expectations. <br></div><div>May I ask researchers why the correct value of hall factor is located at this position of the matrix£¿ <br></div><div>And from which literature should I know the theoretical derivation process of such matrix results£¿<br></div><div><br></div><div>The following is the result of .out file£º</div><div><br></div><div> =============================================================================================<br> BTE<br> =============================================================================================<br><br> Temperature: 300.0000 K<br> Conductivity tensor without magnetic field | with magnetic field [Siemens/m]<br> 0.10189E+00 -0.14253E-17 0.27376E-18 | 0.10189E+00 -0.20777E-05 -0.57270E-18<br> 0.14474E-17 0.10189E+00 0.00000E+00 | 0.25199E-05 0.10189E+00 0.00000E+00<br> 0.32576E-18 0.00000E+00 0.11448E+00 | -0.11383E-18 0.00000E+00 0.11448E+00<br> Mobility tensor without magnetic field | with magnetic field [cm^2/Vs]<br> 0.63593E+03 -0.88962E-14 0.17087E-14 | 0.63593E+03 -0.12968E-01 -0.35745E-14<br> 0.90339E-14 0.63593E+03 0.00000E+00 | 0.15728E-01 0.63593E+03 0.00000E+00<br> 0.20332E-14 0.00000E+00 0.71450E+03 | -0.71045E-15 0.00000E+00 0.71450E+03<br> Hall factor<br> 0.417561E+05 -0.851506E+00 -0.446760E-12<br> 0.103271E+01 0.417561E+05 0.112747E-28<br> -0.261536E-12 0.457976E-17 0.371643E+05</div><div><br></div><div><br></div>Thank you for your attention and look forward to your answers£¡£¡£¡
