Fabrication Method Can Affect the Use of Block Copolymer Thin Films (image) National Institute of Standards and Technology (NIST) Share Print E-Mail Caption The method of creating a thin film can have great effect on the material, such as the orientation of the tiny cylinders in this film proposed for use in computer memory. One method of film creation is far more effective at creating copolymer films with cylinders that stand on end (b), as they must to be usable. Scale bar represents 200 nanometers.
