Depth profile of the chemical composition of the Au-Ag multilayers
Open Research DataSilver and gold multilayers were deposited on a silicon substrate by magnetron sputtering method. Both type, Au and Ag thin films had 2 nm of thickness. Totally structure had thickness of 6 nm (Au-Ag-Au). That prepared multilayers were measured by XPS method. To obtain a depth profile of chemical composition, an Argon ion (Ar+) gun was used for etching...

Marcin Perzanowski dr inż.
PeopleHello, I work in the Department of Magnatic Materials and Nanostructures in the Institute of Nuclear Physics Polish Academy of Sciences in Kraków, Poland. My current research is focused on: (1) exchange bias in multilayers and nanostructures, (2) supermagnetic effects in low-dimensional materials, (3) perpendicular magnetic anisotropy in thin films and nanostructures. Collaborations, comments, and suggestions are welcomed! If...

Design and experimental verification of multi-layer waveguide using pin/hole structure
PublicationThis study presents a novel technique for minimizing RF leakage in metallic hollow waveguides fabricated using the multilayer split-block method. By integrating a pin/hole wall into the split-block multilayers, a substantial reduction of RF leakage can be achieved while reducing the circuit size and mitigating the performance variations. To validate the proposed approach, a slot antenna fed by single ridge waveguide has been prototyped...

Plasma-Based Deposition and Processing Techniques for Optical Fiber Sensing
PublicationPlasma-based techniques are widely applied for well-controlled deposition, etching or surface functionalization of a number of materials. It is difficult to imagine fabrication of novel microelectronic and optoelectronic devices without using plasma-enhanced deposition of thin films, their selective etching or functionalization of their surfaces for subsequent selective binding of chemical or biological molecules. Depending on...

Thermoelectric properties of bismuth-antimony-telluride alloys obtained by reduction of oxide reagents
PublicationThe BieSbeTe alloys with different Bi/Sb/Te ratio were fabricated by an innovative method. For that purpose the oxide reagents were melted at high temperature, then quenched to form pellets, milled to a powder and finally reduced in hydrogen at various temperatures. Complex structures consisting of connected thin layers forming a continuous path between nano- and micrometer size grains have been obtained. The electrical conductivity,...
