  In this note we study thermodynamic geometry of the type 0A black hole
solution in string theory using a variety of different methods (Ruppeiner,
Weinhold and Geometrothermodynamics). Our results indicate that the curvature
invariants are finite for all physical solutions, suggesting that there is no
phase transition. It is also found that the cutoff of the entropy, which is the
singular limit of the theory, appears geometrically in the Weinhold picture as
the thermodynamic cone itself.
