A remarkable theoretical prediction for a crystalline (polymerized) surface is that its Poisson ratio is negative. Using a large-scale Monte Carlo simulation of a simple model of such surfaces we show that this is indeed true. The precise numerical value we find is on a lattice at bending rigidity . This is in excellent agreement with the prediction following from the self-consistent screening approximation of Le Doussal and Radzihovsky.
