I am trying to figure how would I go about finding a dopant element that would fit in a copper lattice? I already have the data for the atomic dimensions and structure (available below), however how would I find a dopant element that would make it a P-Type material? (Relatively new to chemistry, so bear with me if I ask a stupid question)

Atomic dimensions and structure Atomic Radius 145 pm Covalent Radius 138 pm Van der Waals Radius 140 pm Crystal Structure Face Centered Cubic Lattice Angles π/2, π/2, π/2

Lattice Constants 361.49, 361.49, 361.49 pm

Space Group Name Fm_ 3m Space Group Number 225

  • $\begingroup$ Just how do you intend to make Cu, a metal, "p-type"? What do you mean by that? $\endgroup$ – Jon Custer Aug 9 '15 at 16:31
  • $\begingroup$ Copper chalcocite, for example, is a degenerate p-type. To clarify, how would I find a material(s) that would fit within the copper lattice, however a material(s) that leave holes within the valence band. $\endgroup$ – Paul Lemus Aug 9 '15 at 17:13
  • $\begingroup$ Sure, but your example is a compound and not fcc I believe. So, look for other similar transition metal compounds and look at their lattice constants. $\endgroup$ – Jon Custer Aug 9 '15 at 19:57
  • $\begingroup$ So would Copper and Nickel work? They are both fcc I believe, thus would it still leave a valence hole? $\endgroup$ – Paul Lemus Aug 9 '15 at 20:19
