EPW Forum

Dear all,
I dig into the module of tranport_iter.f90 and find:
inv_cell = 1.0d0/omega
! for 2d system need to divide by area (vacuum in z-direction)
IF ( system_2d ) &
inv_cell = inv_cell * at(3,3) * alat
in the last line, what the at(3,3) doea mean? And, does this means the 2D system is considered automatically if
'system_2d' is activated?

Dear Shudong,

2D system are not yet supported in EPW. This is just the start of an implementation but other things need to be fixed to make 2D materials works.

Best wishes,
Samuel
