Abstract
Fluid membranes which experience interaction potentials with a potential barrier are studied by
Monte Carlo simulations. For a symmetric double-well potential, the membranes are found to exhibit
the same critical behavior as the 2-dimensional Ising model even for zero lateral tension. For an
asymmetric adhesion potential with a relatively large potential barrier, the unbound phase is
found to nucleate via the formation of membrane `islands' which implies a discontinuous unbinding
transition.
