The sputter deposited ~Pt/Co/Pt/Ni! multilayer films were studied as possible alternative low Curie temperature multilayers for magneto-optical recording. The Curie temperatures of these multilayers were found to be between 150 and 300 °C, which are much lower than those of Co/Pt multilayers or ~Co,Ni!/Pt multilayers. The coercivities of these multilayers were between 450 and 800 Oe. The Kerr s...

TiAlN/Al2O3 multilayers with different Ar/N2 ratios were deposited on Si substrates in different N2 partial pressure by magnetron sputtering. The crystalline and multilayer structures of the multilayers were determined by a glancing angle X-ray diffractometer (XRD). A nanoindenter was used to evaluate the hardness, the elastic modulus and scratch scan of the multilayers. The chemical bonding wa...

Langmuir–Blodgett (LB) technique has been used to deposit composite multilayers of poly (3-octylthiophene)-cadmium arachidate (POT-CdA) and polyaniline-cadmium arachidate (PANI-CdA). These were used as precursors to develop semiconducting CdS nanoclusters within the conducting polymer based multilayers. The presence of CdS in the multilayers was determined by Fourier transform infrared spectros...

Biopolymer-based multilayers become more and more attractive due to the vast span of biological application they can be used for, e.g., implant coatings, cell culture supports, scaffolds. Multilayers have demonstrated superior capability to store enormous amounts of small charged molecules, such as drugs, and release them in a controlled manner; however, the binding mechanism for drug loading i...

Wideband multilayers designed for various applications in hard X-ray to Extreme UV spectral regions are based on a layered system with layer thicknesses varying largely in depth. However, because the internal structure of a thin film depends on its thickness, this will result in multilayers in which material properties such as density, crystallinity, dielectric constant and effective thickness ...

Influence of NaCl and NaBr and their concentration on assembly of polyelectrolyte multilayers and their compression behavior was studied using poly(diallyldimethylammonium chloride) (PDADMAC) and poly(4-styrenesulfonic acid-co-maleic acid, 1 : 1 SS:MA) sodium salt (PSSMA 1 : 1) as the building blocks. Stepwise growth of the PSSMA/PDADMAC multilayers was characterized by a quartz crystal microba...

Influence of assembly pH on compression and Ag nanoparticle synthesis of polyelectrolyte multilayers was studied using poly(diallyldimethylammonium chloride) (PDADMAC) and poly(4-styrenesulfonic acid-co-maleic acid, 1:1SS:MA) sodium salt (PSSMA 1:1) as the building blocks. The thickest multilayers turned out at pH 4. A homogeneous compression by a silicone rubber stamp increased significantly t...

Commercial EUV lithographic systems require multilayers with higher reflectance and better stability then that published to date. Interface-engineered MoISi multilayers with 70% reflectance at 13.5 nm wavelength (peak width of 0.545 nm) and 71% at 12.7 nm wavelength (peak width of 0.49 nm) were developed. These results were achieved with 50 bilayers. These new multilayers consist of Mo and Si l...
