Although not a prime interest in my group (and never funded), we got heavily involved in high Tc materials. After a false start where we assumed incorrectly that the doping leads to hole in the CuO₂ plane, we eventually showed that the hole is out of the plane, next to the dopant. It leads to a degenerate state with 3 electrons between two degenerate e levels, leading one hole that become conducting above 5% doping and couple to antiferromagnetic Cu at the boundary. This explains most strange properties of Cuprates. We have not been able to predict Tc, but we showed how to order the dopants to double Tc.
