Abstract
Electrical properties of thin W films containing α-W and β-W are studied depending on their thickness, substrate material, phase composition and microstructure. The thickness dependence of phase composition is presented. The theoretical estimations according to quantum mechanical approaches result in good agreement with experimental results for α-W films. The major mechanism of charge carriers scattering in tungsten crystal is the scattering on deformation potential. The thickness dependence of resistivity is investigated experimentally and theoretically, which indicates the dominant contribution of grain-boundary scattering as well as the influence of the interfaces in multilayer structures. The tunneling mechanism is proposed to explain the grain boundary scattering. Transverse magneto-optical Kerr effect indicates the absence of uniaxial symmetry in Co/W system that testifies about the features of tungsten films.
期刊介绍：
Current Applied Physics (Curr. Appl. Phys.) is a monthly published international journal covering all the fields of applied science investigating the physics of the advanced materials for future applications.
Other areas covered: Experimental and theoretical aspects of advanced materials and devices dealing with synthesis or structural chemistry, physical and electronic properties, photonics, engineering applications, and uniquely pertinent measurement or analytical techniques.
Current Applied Physics, published since 2001, covers physics, chemistry and materials science, including bio-materials, with their engineering aspects. It is a truly interdisciplinary journal opening a forum for scientists of all related fields, a unique point of the journal discriminating it from other worldwide and/or Pacific Rim applied physics journals.
Regular research papers, letters and review articles with contents meeting the scope of the journal will be considered for publication after peer review.
The Journal is owned by the Korean Physical Society.
