2011 journal article

Finite-size effects in nanocomposite thin films and fibers

PHYSICAL REVIEW E, 84(2).

By: D. Stevens n, E. Skau n, L. Downen n, M. Roman n & L. Clarke n 

MeSH headings : Monte Carlo Method; Nanocomposites / chemistry; Probability
TL;DR: Findings indicate that sample shape, as well as relative size, influences percolation in the finite-size regime, as the sample became quasi-one-dimensional. (via Semantic Scholar)
