Electrically driven magnetism on a Pd thin film

Fabrication of antiferromagnetic α-Cr2O3(0001) thin film and influence on magnetism of ultrathin Co film

We have investigated the fabrication of α-Cr2O3(0001) thin film on a Au(111) surface and the effect of the antiferromagnetic feature of α-Cr2O3(0001) on the magnetic properties of ultrathin Co film on α-Cr2O3(0001). Highly oriented α-Cr2O3(0001) thin film is fabricated by oxidizing Cr(110) thin film grown on a Au(111) surface. Upon the oxidization of threefold symmetric Cr(110) thin film, the α...

Grazing-incidence X-ray Technique for Surface, Interface, and Thin-film Analysis

Two applications of grazing-incidence X-rays, namely the grazing-incidence diffraction for characterization of epitaxial films and depth profiling of residual stresses are described. In a grazing-incidence experiment, the detector is placed in a horizontal plane parallel to the film surface to record diffraction from lattice planes which are perpendicular to the surface. An example on the analy...

Morphological influence on surface–wave propagation at the planar interface of a metal film and a columnar thin film

The selection of a higher vapor deposition angle when growing a columnar thin film (CTF) leads to surface– wave propagation at a planar metal–CTF interface with phase velocity of lower magnitude and shorter propagation range. Acordingly, a higher angle of plane–wave incidence is required to excite that surface wave in a modified Kretschmann configuration. c © Anita Publications. All rights rese...

Effect of Surface Energy on Pentacene Thin-Film Growth and Organic Thin Film Transistor Characteristics

In this study, we discuss pentacene-based organic thin films grown on a self-assembled monolayer (SAM)-treated dielectric with various functional groups and molecular lengths. The functional groups and molecular lengths on the dielectric surface were modified using a SAM treatment followed by ultra violet (UV) light exposure. Surface energy was used to observe the surface polarity variation dur...
