Abstract
The equilibrium structure of self-avoiding two-dimensional tethered membranes embedded in a space of dimension
d>2 are studied using molecular dynamics simulations for
. For embedding dimension
, the membranes crumple while they remain flat for
. In the crumbled phase, the radius of gyration
increases as
, where
L is the linear size of the uncrumpled surface, and
is significantly larger than the simple Flory estimate
. For
d=4, the membrane remains flat, even in the presence of site-dilution, indicating that as for
d=3, random site-dilution alone is not sufficient to produce crumpling of two-dimensional membranes.
