Quantum-well states in copper thin films
Article Abstract:
Quantum-well states can be realized experimentally in a thin film, confining the electron motion in a direction usual to the film. The presence of such states in layered metallic nanostructures is thought to underlie several phenomena. Photoemission experiments have shown the spatial variation of the quantum-well wavefunction in a thin copper film, and the results confirm that an envelope function modulates the amplitude of electron waves confined in a metallic thin film.

Nanodomain control in copolymer thin films
Article Abstract:
Diblock copolymers consist of two chemically distinct chains that are covalently bound at one end. The orientation of diblock copolymer microdomains can be controlled by eliminating all preferential interfacial segragation of the components through the anchoring of random copolymers. A model system used symmetric diblock copolymers of polystyrene and poly(methyl methacrylate) chemically grafted to a silicon substrate and fixed to the polymer-air interface by end-linking.

Friction measurements on phase-separated thin films with a modified atomic force microscope
Article Abstract:
Friction force microscopes (FFM) represents a refined imaging technique that can clarify compositional domains on thin films down to a resolution of about five angstroms. FFMs achieve this degree of resolution by measuring normal and lateral forces on the scanning tip. Moreover, FFMs can obtain particulars about chemical compositional as well as about film topography unlike the standard atomic force microscopes.
