We investigate exciton bound‐state formation and crystallization effects in two‐dimensional electron‐hole bilayers. Performing unbiased path integral Monte Carlo simulations all quantum and Coulomb correlation effects are treated on first principles. We analyze diverse pair distribution functions in dependence on the layer separation, particle density and hole‐to‐electron mass ratio and derive a schematic phase diagram for the neutral mass‐asymmetric bilayer system. Our simulations reveal a great variety of possible phases namely an exciton gas, an exciton crystal, an electron‐hole liquid and a hole crystal embedded in an electron gas (© 2012 WILEY‐VCH Verlag GmbH & Co.
