  We obtain the thermodynamic geometry of a (2+1) dimensional strongly coupled
quantum field theory at a finite temperature in a holographic set up, through
the gauge/gravity correspondence. The bulk dual gravitational theory is
described by a (3+1) dimensional charged AdS black hole in the presence of a
massive charged scalar field. The holographic free energy of the (2+1)
dimensional strongly coupled boundary field theory is computed analytically
through the bulk boundary correspondence. The thermodynamic metric and the
corresponding scalar curvature is then obtained from the holographic free
energy. The thermodynamic scalar curvature characterizes the superconducting
phase transition of the boundary field theory.
