Between Two and Three Dimensions

One of the most glamorous aspects of monolayer films is their thinness, and another is their two dimensionality.

Even more confusing is that a film can be two dimensional and three dimensional—and some‐where in between—at the same time. A simple change of temperature can change a film’s dimensionality.
