<DIV>Hi! All</DIV>
<DIV>I'm trying to calculate the quantum conductance of quasi one dimension structure with Wannier90 and PWscf. </DIV>
<DIV>But the one dimension band structure of suppercell is weird: bands with high energy seem very "crowded".</DIV>
<DIV>I meet this problem when calculating Al nanowire and graphene nanoribbon. It seems a computation error as</DIV>
<DIV>energy seems to be limitted in a small range.</DIV>
<DIV>I have raised the value of cutoff and distance between nanoribbons in directions perpendicular to transport,</DIV>
<DIV>but results changed little.</DIV>
<DIV>My friend plots the bands of graphene nanoribbon with fplo, which can be a reference I think.</DIV>
<DIV> </DIV>
<DIV>The input files and bands are in attachment.</DIV>
<DIV> </DIV>
<DIV>Thank you very much!</DIV>
