Abstract
Multiple coherent scattering may be observed in electron diffraction if the sample under investigation is very thick or its structure is perfectly ordered. Here we report surprising experimental results from ultrathin free-standing crystal-B films of 4-n-pentylbenzenethio-4′-n-tetradecyloxybenzoate (14S5) using electron diffraction. Multiple coherent scattering is observed down to two-layer films. Our result indicates that long-range crystalline order can be developed in a quasi-two-dimensional experimental system.
