Dear QE users,<br><br> I did a band structure calculation for bulk 3C-SiC (zincblend structure) using ibrav=2, and using high K_points of FCC's BZ including :K, gamma, X, L, U and W. I got a good band structure with indirect band gap from gamma to X point (which agree well with literature). <br>
<br> However, I did the same calculation process using ibrav=0 to confirm my band structure, now I used k-point path of simple cubic BZ including : X,M,R, and gamma points. But my band structure do not seem to be correct. <br>
<br> I have attached the input files and the plots of band structure for two cases here for your review. Please let me know what I did wrong. If you need more information, please also let me know. I really look forward for any suggestion you can give me.<br>
