  * [[https://www.materialsproject.org/|The Materials Project]]  LBNL. Log in with google credentials (or other). Remember that band structures are all calculated by DFT/GGA so all band gaps are underestimated and all lattice parameters are too large by a few percent (this shifts XRD patterns).

  * [[http://www.aflowlib.org/|AFLOWLIB]]
  * [[http://mits.nims.go.jp/index_en.html|MATNavi]].  The materials database of NIMS (Japan).  Free.  Just register
