  We show that charged black holes in Anti-de Sitter spacetime can undergo a
third order phase transition at a critical temperature in the presence of
charged fermions. In the low temperature phase, a fraction of the charge is
carried by a fermion fluid located a finite distance from the black hole. In
the zero temperature limit the black hole is no longer present and all charge
is sourced by the fermions. The solutions exhibit the low temperature entropy
density scaling s~T^{2/z} anticipated from the emergent IR criticality of
recently discussed electron stars.
