<div dir="ltr"><div><div><div><div><div><div>Dear QE experts,<br><br></div>I am trying
to calculate band structure for Full Heusler Fe2TiSn system. But instead
of getting the usual band gap(0.06eV), in my case the conduction and
valence band overlaps except otherwise the band structure is almost
same.<br><br></div>I have tried to do the same calculation using Pbesol pseudopotential and ONCV_PBE pseudopotential, but got the same result. <br><br></div>I
am atttaching my input files and output band structure. Can somebody tell me what is the mistake I am
doing?<br><br></div>Thanking you in advance,<br><br></div>Sayan Chaudhuri</div><div>Research Scholar<br></div>IIT Indore</div>
